What this calculator does
MET-minutes per week works out weekly physical activity volume in MET-minutes, checked against the WHO activity guideline. Enter your own figures above and the answer updates as you type: nothing is fixed in the code, so the result reflects exactly the numbers you supply.
The formula this calculator evaluates is printed under the tool and explained below, so you can check the working by hand or reuse it in a spreadsheet.
The formula
The inputs explained
| Field | What to enter |
|---|---|
| Moderate activity (e.g. brisk walking, ~4 MET) (min/week) | A number, measured in min/week. Starts at 150. |
| MET value of moderate activity | A number. Starts at 4. |
| Vigorous activity (e.g. running, ~9 MET) (min/week) | A number, measured in min/week. Starts at 60. |
| MET value of vigorous activity | A number. Starts at 9. |
Worked examples
Every figure in the tables below is produced by this page’s own calculator at build time, so the numbers and the tool always agree. Select any row to load that scenario.
How the answer changes with moderate activity (e.g. brisk walking, ~4 met)
Every other input is held at the calculator’s starting values while moderate activity (e.g. brisk walking, ~4 met) varies. Select any row to load that scenario into the calculator.
| Moderate activity (e.g. brisk walking, ~4 MET) (min/week) | Total MET-minutes per week | WHO guideline check | Moderate activity contribution |
|---|---|---|---|
| 75 | 840 | Meets the baseline WHO guideline (450+ MET-min/week) | 300 MET-min |
| 113 | 992 | Meets the higher WHO target (900+ MET-min/week) | 452 MET-min |
| 150 | 1,140 | Meets the higher WHO target (900+ MET-min/week) | 600 MET-min |
| 225 | 1,440 | Meets the higher WHO target (900+ MET-min/week) | 900 MET-min |
| 300 | 1,740 | Meets the higher WHO target (900+ MET-min/week) | 1,200 MET-min |
| 450 | 2,340 | Meets the higher WHO target (900+ MET-min/week) | 1,800 MET-min |
