What does the watts-to-calories calculator do?

It converts your cycling power output into energy. Enter your average power in watts and duration, and it returns the mechanical work done in kilojoules along with the calories you burned, helping you match training effort to nutrition.

How do watts convert to calories burned?

Average watts times duration in seconds gives work in joules, divided by 1,000 for kilojoules. Conveniently, kilojoules of work roughly equal the calories burned, because human cycling efficiency of about 20–25% nearly cancels the kJ-to-kcal conversion factor.

Why do kilojoules roughly equal calories on a bike?

Cyclists are only about 20–25% efficient, so for every kilojoule of mechanical work you actually expend about four to five kilojoules of energy. Since one calorie is about 4.18 kilojoules, the two numbers end up nearly equal, making kJ a handy calorie estimate.

Watts na Kalorieë Sakrekenaar

Drywingmeters rapporteer watts en kilojoule, maar die meeste mense dink in kalorieë. Voer jou gemiddelde drywing en hoe lank jy gery het in, en hierdie sakrekenaar gee die meganiese werk in kilojoule en die kalorieë wat jy verbrand het terug, met 'n tipiese fietsrydoeltreffendheid van ongeveer 24%. Gebruik dit om 'n rit teen jou voeding na te gaan, pogings te vergelyk, of te verstaan hoekom kilojoule werk en verbrande kalorieë omtrent gelyk uitkom op 'n fiets.

Meganiese werk is drywing × tyd: watts maal sekondes gee joule, hier in kilojoule getoon. Fietsryers verbrand meer energie as daardie werk omdat spiere net ongeveer 24% doeltreffend is — die res word hitte. Om die werk deur 0.24 te deel en na kilokalorieë om te skakel, is hoekom 'n nuttige duimreël sê verbrande kalorieë ≈ kilojoule werk. Dit tel net oefeningsenergie, nie jou rustende metabolisme nie, en aanvaar tipiese fietsrydoeltreffendheid.
