照明是每单位区域表面上的总发光通量。它以Lux（LX）为单位。
1 fc·h = 1 cd/m²
1 cd/m² = 1 fc·h
例子:
将15 脚坎德尔小时转换为每平方米烛台：
15 fc·h = 15 cd/m²
| 脚坎德尔小时 | 每平方米烛台 |
|---|---|
| 0.01 fc·h | 0.01 cd/m² |
| 0.1 fc·h | 0.1 cd/m² |
| 1 fc·h | 1 cd/m² |
| 2 fc·h | 2 cd/m² |
| 3 fc·h | 3 cd/m² |
| 5 fc·h | 5 cd/m² |
| 10 fc·h | 10 cd/m² |
| 20 fc·h | 20 cd/m² |
| 30 fc·h | 30 cd/m² |
| 40 fc·h | 40 cd/m² |
| 50 fc·h | 50 cd/m² |
| 60 fc·h | 60 cd/m² |
| 70 fc·h | 70 cd/m² |
| 80 fc·h | 80 cd/m² |
| 90 fc·h | 90 cd/m² |
| 100 fc·h | 100 cd/m² |
| 250 fc·h | 250 cd/m² |
| 500 fc·h | 500 cd/m² |
| 750 fc·h | 750 cd/m² |
| 1000 fc·h | 1,000 cd/m² |
| 10000 fc·h | 10,000 cd/m² |
| 100000 fc·h | 100,000 cd/m² |
