Estimated Oxygen Consumption Calculator

Estimate oxygen consumption during rest or exercise using body weight, activity intensity, and duration. This is an educational physiology tool, not a lab VO₂ test.

Used to estimate total oxygen use per minute.
Each activity uses a rough metabolic equivalent.
Used to estimate total oxygen consumed.
Affects interpretation, not the basic oxygen formula.
Choose whether to show relative and absolute values.

How we calculate

We estimate oxygen consumption from an approximate metabolic equivalent. One MET is treated as about 3.5 mL/kg/min. Total oxygen used is then estimated across the selected duration.
