功率是完成工作或能量转移的速度。它以瓦（w）为单位进行测量。
1 kcal/s = 1,000 cal/s
1 cal/s = 0.001 kcal/s
例子:
将15 千瓦时第二转换为每秒卡路里：
15 kcal/s = 15,000 cal/s
| 千瓦时第二 | 每秒卡路里 |
|---|---|
| 0.01 kcal/s | 10 cal/s |
| 0.1 kcal/s | 100 cal/s |
| 1 kcal/s | 1,000 cal/s |
| 2 kcal/s | 2,000 cal/s |
| 3 kcal/s | 3,000 cal/s |
| 5 kcal/s | 5,000 cal/s |
| 10 kcal/s | 10,000 cal/s |
| 20 kcal/s | 20,000 cal/s |
| 30 kcal/s | 30,000 cal/s |
| 40 kcal/s | 40,000 cal/s |
| 50 kcal/s | 50,000 cal/s |
| 60 kcal/s | 60,000 cal/s |
| 70 kcal/s | 70,000 cal/s |
| 80 kcal/s | 80,000 cal/s |
| 90 kcal/s | 90,000 cal/s |
| 100 kcal/s | 100,000 cal/s |
| 250 kcal/s | 250,000 cal/s |
| 500 kcal/s | 500,000 cal/s |
| 750 kcal/s | 750,000 cal/s |
| 1000 kcal/s | 1,000,000 cal/s |
| 10000 kcal/s | 10,000,000 cal/s |
| 100000 kcal/s | 100,000,000 cal/s |
