Pace and watts

Concept2 calories per hour to watts and split

Exact

A Concept2 monitor showing 1000 calories per hour is about 203 watts, a 1:59.8 split. This chart converts every calories per hour figure from 400 to 1800, in steps of 100, to watts and the 500m split.

  • Treat calories as a guide to effort, not an exact burn. Compare sessions on watts or split.
  • The monitor adds a fixed 300 calorie resting allowance, worked out for a 175 lb (79.5 kg) person.
Worked example

Worked example

At 1000 calories per hour, 700 calories are left after the 300 resting allowance. That is 203.4 watts, a 1:59.8 split.

How it is worked out

Watts come back from the monitor figure by taking off the fixed 300 calorie resting allowance, then dividing by four times 0.8604: watts = (calories per hour − 300) ÷ (4 × 0.8604). That allowance is worked out for a 79.5 kg (175 lb) person, the reference weight the converter uses when no body weight is entered. The 500m split then comes from the watts: split = 500 × cube root of (2.80 ÷ watts).
