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.

Amamitha amandla abika ama-watts nama-kilojoule, kodwa abantu abaningi bacabanga ngamakhalori. Faka amandla akho aphakathi nokuthi ugibele isikhathi esingakanani, futhi lesi sibali sibuyisela umsebenzi wemishini ngama-kilojoule namakhalori owashisile, kusetshenziswa ukusebenza okujwayelekile kokugibela cishe ngo-24%. Sisebenzise ukuhlola ukugibela maqondana nokudla kwakho, ukuqhathanisa imizamo, noma ukuqonda ukuthi kungani ama-kilojoule omsebenzi namakhalori ashisiwe egcina elingana cishe ebhayisikilini.

Umsebenzi wemishini ungamandla × isikhathi: watts × amasekhondi unika ama-joule, aboniswe lapha ngama-kilojoule. Abagibeli bamabhayisikili bashisa amandla amaningi kunalowo msebenzi ngoba imisipha isebenza ngo-24% kuphela — okusele kuba ukushisa. Ukuhlukanisa umsebenzi ngo-0.24 nokuwuguqulela kuma-kilocalorie yikho okwenza umthetho oluwusizo wokuthi amakhalori ashisiwe ≈ ama-kilojoule omsebenzi. Lokhu kubala amandla okuzivocavoca kuphela, hhayi i-metabolism yakho yokuphumula, futhi kucabangela ukusebenza okujwayelekile kokugibela ibhayisikili.
