You’re scrolling through a group chat, or maybe you’re looking at a weather report, or—heaven forbid—you’re reading a technical manual about metallurgy. Suddenly, you see it. Three letters. M-E-T.
What does met mean?
Honestly, the answer depends entirely on who you’re talking to. If it's your friend texting about a Tinder date, they’re probably just using the past tense of "meet." But if you’re looking at a fitness tracker or a medical chart, things get a whole lot more complicated. Language is messy. We shorten everything because we're in a rush, but that leaves everyone else guessing.
The Most Common Way We Use Met
Let's start simple. In everyday English, "met" is just the past tense and past participle of "meet." You met someone for coffee. You've met your match. It's one of those irregular verbs that we don't even think about until a kid or a non-native speaker asks why we don't say "meeted."

But in the digital age, "met" has taken on a life of its own as an acronym. It pops up in gaming, in the workplace, and in science. If you see someone post "MET" in all caps, they aren't talking about seeing a friend at the park.
When "Met" Is Actually a Medical Metric
If you’ve ever used a treadmill or a high-end Garmin watch, you might have seen a "MET" value. This isn't just some random number to make you feel like you're working hard.
In the world of exercise science, MET stands for Metabolic Equivalent of Task.
Think of it as a way to measure how much energy your body is using compared to when you're just sitting still on the couch. One MET is defined as the amount of oxygen consumed while at rest, which is roughly $3.5\text{ ml}$ of oxygen per kilogram of body weight per minute.
It's a ratio.
If you are doing an activity that is 5 METs, you are burning five times as many calories as you would be if you were just staring at the wall. Doctors use this. The American Heart Association uses this to track cardiovascular health. It’s a universal language for physical exertion that levels the playing field between a 120-pound marathoner and a 250-pound powerlifter.
Breaking down the effort levels
- 1.0 to 1.5 METs: This is basically "sedentary." Watching TV, sitting at a desk, or reading this article.
- 1.6 to 3.0 METs: Light intensity. Think slow walking or washing the dishes.
- 3.0 to 6.0 METs: Moderate intensity. Brisk walking (about 3 to 4 mph) falls here.
- Over 6.0 METs: Vigorous intensity. Running, competitive soccer, or shoveling heavy snow.
If a doctor tells you that you need to clear 10 METs on a stress test, they are literally measuring whether your heart can handle the demand of intense physical labor. It’s one of the most reliable predictors of long-term mortality.
That Big Museum in New York
We can't talk about what "Met" means without mentioning The Metropolitan Museum of Art in New York City. People just call it "The Met."
It’s one of the largest and most visited art museums in the world. But here's the kicker: there isn't just one. There’s the main building on Fifth Avenue, and then there’s The Met Cloisters in Upper Manhattan, which focuses on medieval European art and architecture.
When someone says, "I'm going to the Met," they’re usually talking about the Fifth Avenue giant. It’s a cultural shorthand that has existed for over a century. If you're into fashion, you also know about the Met Gala. That’s the annual fundraising benefit for the Museum's Costume Institute. It’s basically the "Oscars of Fashion," and it's where celebrities dress up in outfits that make the rest of us go, "Wait, is that a cat suit?"
The Meteorological Side of Things
Flip on the news in the UK or parts of Europe, and you’ll hear people talk about "The Met Office."
In this context, Met is short for Meteorology.

The Met Office is the UK’s national weather service. It’s one of the most advanced weather forecasting organizations on the planet. They don't just tell you if it’s going to rain; they provide data for aviation, shipping, and government defense.
It’s interesting how "The Met" can mean a quiet afternoon looking at Egyptian sarcophagi in New York, or a frantic warning about a Category 4 hurricane in London. Context is everything.
Met in the Workplace: Meetings and Targets
In the corporate world, "MET" often shows up in internal emails as an acronym for Meeting.
"Did you catch the MET notes?"
It’s lazy, sure. But in a world of "ASAPs" and "FYIs," it was bound to happen. However, there is a more formal version of MET used in project management and manufacturing: Mission Essential Task.
This comes from military roots. A Mission Essential Task is something that must happen for the overall goal to be successful. If you fail a MET, the mission fails. Many tech companies have adopted this language to prioritize their "sprints" or quarterly goals.
The "Met" in Biology and Chemistry
If you’re a science nerd, or maybe you’re just reading the back of a supplement bottle, you’ll see "Met" used as an abbreviation for Methionine.
Methionine is an essential amino acid. Your body can’t make it on its own; you have to get it from food like eggs, meat, or nuts. It’s the "start" signal for protein synthesis. Basically, your body uses Met to kick off the process of building new proteins.
In a completely different branch of science, "met" is a prefix used in geology and chemistry. Metamorphic rocks are rocks that have changed form due to heat and pressure. Metallurgy is the study of metals.
And then there's Metformin.
Metformin is the most widely prescribed medication for Type 2 diabetes globally. Patients and doctors often shorten it to "Met" in casual conversation. "Are you still on the Met?" is a common question in endocrine clinics. It helps lower glucose production in the liver and makes your body more sensitive to insulin.
Policing and The Met
If you live in London, "The Met" has a very specific, sometimes controversial meaning: The Metropolitan Police Service.
Founded by Robert Peel in 1829, it was the first modern, professional police force. When Londoners talk about "The Met," they aren't talking about art or weather—they're talking about the cops.
It’s a massive organization with over 40,000 employees. Because of its size and history, it often finds itself in the crosshairs of political debate. Whether it's policing a protest or handling a high-profile investigation, "The Met" is a household name in the UK.
Gaming and "The Meta"
Wait, is "Met" the same as "Meta"?
Not exactly, but they get confused a lot. In gaming, the "Meta" (Most Effective Tactics Available) refers to the current strongest strategies.
However, in some RPGs (Role-Playing Games), "Met" is used as a shorthand for Metahuman. In settings like Shadowrun or various superhero games, a "met" is someone with extraordinary abilities or a non-human lineage.
If you see a player say, "I'm playing a Met," they aren't talking about a baseball player.

The New York Mets
Speaking of baseball...
You can't discuss this word without acknowledging the New York Mets.
They joined Major League Baseball in 1962 to replace New York's departed National League teams, the Brooklyn Dodgers and the New York Giants. The name "Mets" was chosen because it was short, easy to put in headlines, and tied back to the corporate name of the club: the Metropolitan Baseball Club, Inc. The Mets have a unique spot in sports history. They’ve had incredible highs (the 1969 "Miracle Mets") and some pretty hilarious lows. Being a "Mets fan" is often described as a test of character.
How to Determine Which "Met" You're Looking At
Since the word is everywhere, you have to look at the surrounding clues.
- Is there a number next to it? It’s probably a Metabolic Equivalent (health/fitness).
- Is it "The" Met? It’s likely the museum (NYC), the police (London), or the weather service (UK).
- Is it in a medical context? It’s likely Methionine or Metformin.
- Is it in an email about a calendar invite? It’s a meeting.
Why This Word Is a Linguistic Chameleon
Words like "met" survive because they are short. Human beings are inherently efficient—or lazy, depending on how you look at it. We like one-syllable sounds.
The problem is that as our world becomes more specialized, we keep reusing the same short sounds for completely different things. A doctor and a baseball coach can use the same word and mean something 180 degrees apart.
It’s a reminder that communication isn't just about the words you say; it's about the shared reality you have with the person listening.
Practical Steps for Clarity
If you're writing or speaking and want to make sure you're understood, here’s how to handle the "met" confusion:
- Specify the "The": Don't just say "Met." Say "The Met Office" or "The Met Museum" to save everyone five minutes of confusion.
- Capitalization matters: In writing, keep "MET" capitalized if it's an acronym (like the fitness metric) and lowercase "met" if it's just the past tense of meet.
- Define your acronyms: If you are writing a business report, define "Mission Essential Task (MET)" the first time you use it. Don't assume your new hire knows your office lingo.
- Check your fitness apps: If you're trying to lose weight, look at your MET scores. Aiming for activities that are 6.0 METs or higher will give you the most "bang for your buck" in terms of time spent exercising.
- Contextualize in Chat: If you're texting "Met," and it's not immediately obvious, just add a noun. "Met the deadline" vs "Met at 5."
Language moves fast. Tomorrow, "met" might mean something entirely new in a VR world or a new social media app. But for now, you’ve got the full spectrum. Whether you’re tracking your heart rate, heading to a baseball game, or admiring a Picasso, you know exactly what’s going on.
