MET-minutes are the standard unit public health organizations use to measure physical activity volume in a way that’s comparable across completely different activities — a MET-minute figure from swimming laps and a MET-minute figure from brisk walking mean genuinely the same thing in terms of total physiological effort, even though the activities feel nothing alike. This calculator multiplies an activity’s MET value (Metabolic Equivalent of Task, a measure of how many times harder an activity is than sitting still) by its duration in minutes to produce a single MET-minutes figure that’s directly comparable across any activity you choose.
Below the calculator you’ll find a manual step-by-step walkthrough of the MET-minutes formula, what MET values actually represent, why researchers and public health bodies favor this unit, how MET-minutes compare to official weekly activity guidelines, common mistakes people make when tracking activity this way, and an expanded FAQ.

Step-by-Step: How to Calculate MET-Minutes by Hand
The formula is deliberately simple: MET-minutes = MET value × duration in minutes. There’s no unit conversion or intermediate step required — you just need an accurate MET value for the specific activity and intensity you performed, which can be looked up from a standard MET values reference (the Compendium of Physical Activities is the most widely cited source) or estimated from this calculator’s preset dropdown.
Worked example: 45 minutes of general jogging, which has a standard MET value of about 6.0. MET-minutes = 6.0 × 45 = 270 MET-minutes for that single session. If you did that same jogging session five days in a week, your weekly total would be 270 × 5 = 1,350 MET-minutes, comfortably inside the upper range that major health guidelines associate with substantial additional health benefit, well beyond the minimum threshold most guidance considers meaningful.
What a MET Value Actually Represents
One MET is defined as the energy cost of sitting quietly at rest, roughly equivalent to burning 1 kilocalorie per kilogram of body weight per hour. An activity with a MET value of 6 therefore requires roughly six times the energy expenditure of sitting still — this is what lets MET values compare wildly different activities on the same numerical scale, from light housework (around 2-3 MET) up to vigorous running or competitive sports (8 MET and well above).
Because MET values are standardized and activity-specific rather than personalized to an individual’s fitness level, they provide a consistent, repeatable way to log activity volume over time without needing a heart rate monitor, power meter, or other personal biometric device — you just need to know roughly what activity you did and for how long.
Why Researchers and Public Health Bodies Prefer MET-Minutes
Before MET-minutes became standard, physical activity research struggled to compare studies that measured “exercise” in inconsistent ways — some counted only structured workouts, others counted any movement, and intensity was rarely captured at all. MET-minutes solved this by giving researchers a single, activity-agnostic unit that captures both how hard an activity is and how long it lasted, which makes it possible to meaningfully pool and compare data from completely different studies, populations, and activity types.
This is also why MET-minutes (sometimes expressed as MET-hours, simply MET-minutes divided by 60) show up throughout large epidemiological studies linking physical activity to reduced risk of cardiovascular disease, certain cancers, and all-cause mortality — the unit lets researchers establish dose-response relationships, showing that health benefit tends to increase with weekly MET-minute totals up to a point, which is exactly where public health guidelines like the 500-1,000 weekly range originate from.
MET-Minute Session Benchmarks at a Glance
These are the exact thresholds this calculator uses to categorize a single session’s MET-minute total:
| MET-Minutes | Category | Example |
|---|---|---|
| 1,500+ | Weekly Goal Met in One Session | A very long or very intense single session |
| 500 – 1,499 | High-Value Session | An hour or more of vigorous activity |
| 150 – 499 | Solid Moderate Session | 30-60 minutes of moderate activity |
| Below 150 | Light Session | A short walk or brief light activity |
How MET-Minutes Compare to Weekly Activity Guidelines
Major public health bodies, including the World Health Organization, frame their physical activity recommendations partly in MET-minute terms: roughly 500 to 1,000 MET-minutes per week is commonly cited as the range associated with substantial health benefits, achievable through combinations like 150 minutes of moderate activity (about 3-6 MET) or 75 minutes of vigorous activity (6+ MET) spread across the week. This calculator’s progress bar compares your entered session against the midpoint of that commonly cited weekly range, so you can see roughly what fraction of a full week’s target a single session represents.
Because MET-minutes accumulate additively across activities and days, the framework works equally well whether someone gets their weekly total from one long session, several medium sessions, or many short bouts spread throughout the week — the total MET-minute figure is what public health guidance actually tracks, not the specific pattern of how it was accumulated.
Common Mistakes When Tracking MET-Minutes
The most frequent mistake is using an inaccurate or overly generic MET value — “running” alone covers a huge range from a gentle 6 mph jog (about 8-9 MET) to a hard sprint pace (well over 12 MET), so picking a MET value specific to your actual pace and intensity matters for an accurate total. A second mistake is forgetting that MET values already account for body-weight-relative effort in a general population sense, so no additional body-weight adjustment is needed on top of the standard MET-minutes formula, unlike calorie-burn calculations which do require multiplying by individual body weight.
A third mistake is comparing MET-minute totals across people as if they represent identical relative effort — a MET value is calibrated to an average adult, so the same nominal activity can feel considerably harder or easier for a given individual depending on their personal fitness level, even though the MET-minutes figure itself stays the same.
FAQ
What’s the difference between MET-minutes and calories burned?
MET-minutes measure relative activity intensity over time on a standardized scale, while calories burned convert that into an actual energy figure specific to your body weight — the two are related but MET-minutes stays consistent regardless of who’s doing the activity.
Where do standard MET values come from?
Most published MET values trace back to the Compendium of Physical Activities, a research reference that assigns MET values to hundreds of specific activities and intensities based on measured oxygen consumption studies.
Is 500-1,000 weekly MET-minutes a hard requirement for health benefits?
No — it’s a commonly cited reference range associated with substantial benefit in population studies, but any amount of regular activity above a sedentary baseline provides meaningful health value, and more active weeks generally provide additional benefit beyond that range.
Can MET-minutes be negative or represent very low activity?
No — MET-minutes can’t go below roughly the resting baseline, since even very light activity carries a MET value close to but still above 1.0, representing energy expenditure only slightly above quiet rest.
Should MET-minutes replace calorie tracking for weight management?
Not necessarily — MET-minutes are a useful, standardized way to track activity volume and compare against health guidelines, but calorie tracking remains more directly relevant for weight management goals, and the two metrics are best used alongside each other rather than as substitutes.
Does age or sex change how MET values are applied?
Standard MET values are generally applied the same way regardless of age or sex, since they’re calibrated to a standardized average metabolic rate, though some researchers note that individual metabolic rates can vary enough to make personalized calorie estimates somewhat less precise for any single specific person.
Do fitness trackers calculate MET-minutes automatically?
Many do, typically by estimating activity intensity from heart rate or motion data and matching it to an internal MET lookup table, though the specific MET values and methodology can vary somewhat between different devices and brands.
