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.

Kalkulator Watts ke Kalori

Meter kuasa melaporkan watts dan kilojoule, tetapi kebanyakan orang berfikir dalam kalori. Masukkan kuasa purata anda dan berapa lama anda berbasikal, dan kalkulator ini memulangkan kerja mekanikal dalam kilojoule serta kalori yang anda bakar, menggunakan kecekapan berbasikal biasa kira-kira 24%. Gunakannya untuk menyemak perjalanan terhadap pemakanan anda, membandingkan usaha, atau memahami mengapa kilojoule kerja dan kalori dibakar berakhir hampir sama di atas basikal.

Kerja mekanikal ialah kuasa × masa: watts × saat menghasilkan joule, ditunjukkan di sini dalam kilojoule. Penunggang basikal membakar lebih banyak tenaga daripada kerja itu kerana otot hanya kira-kira 24% cekap — selebihnya menjadi haba. Membahagikan kerja dengan 0.24 dan menukar kepada kilokalori menjelaskan mengapa petua praktikal yang berguna ialah kalori dibakar ≈ kilojoule kerja. Ini mengira tenaga senaman sahaja, bukan metabolisme rehat anda, dan mengandaikan kecekapan berbasikal yang biasa.
