Calories burned calculator processes your input in this browser. Inputs and results are excluded from analytics. Recent tools save tool names, visit counts and last-visit times. Saved tools store only their names. Draft saving is optional and stays on this device; delete saved text with the draft controls. Loading text from a URL is optional and contacts that server; its URL and your IP address are visible to the server. An optional “Use in” action keeps a handoff in this tab. The next tool removes it on arrival and ignores it if more than a minute has passed.

Copy link includes the inputs you choose to share in the address. Anyone with that link can reopen them. Files and generated results are excluded. Password and key tools share settings only.

Precision and calculation record

Decimal places in numeric results and text downloads

Rounding changes displayed numbers, not the calculation. Text, fractions, matrices and CSV schedules keep their own formatting. Automatic keeps up to 12 significant digits, with money shown to cents where applicable.

Saved scenario

Save the current answer, then change an input to compare. This clears when you leave.

Formula and assumptions

Adult Compendium presets apply to ages 19-59 and the exact activity described. Choose the nearest exact activity or provide your own MET; activities with different intensities are not combined. Gross calories include resting energy during that time. The extra-above-rest estimate subtracts one standard MET. Population estimates can differ from individual measurements; this is not an exercise prescription.

Automatic precision shows numbers to 12 significant digits. Thousands separators such as 1,000 are accepted; use a dot for decimals.

Use +, −, ×, ÷, parentheses and %. A percentage is divided by 100. This does not change the main tool.

Reset reloads the tool with its starting values and releases open files and device controls. Saved drafts stay on this device until you delete them.

Links include your inputs and settings. Anyone with the link can see them, so leave out private text. Files and generated results are left out; random draws run again.

A worked example

For body weight (kg) = 70, active time (minutes) = 30, activity from the 2024 adult compendium = 17190 - Walking, 2.8 to 3.4 mph, level, moderate pace, firm surface (3.8 MET), your own met value (only for custom activity) = 3.8, estimated gross calories (kcal) = 139.65.

Before you use the result
