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 cd/m² = 1 II
1 II = 1 cd/m²
例子:
将15 每平方米烛台转换为照明指数:
15 cd/m² = 15 II
| 每平方米烛台 | 照明指数 |
|---|---|
| 0.01 cd/m² | 0.01 II |
| 0.1 cd/m² | 0.1 II |
| 1 cd/m² | 1 II |
| 2 cd/m² | 2 II |
| 3 cd/m² | 3 II |
| 5 cd/m² | 5 II |
| 10 cd/m² | 10 II |
| 20 cd/m² | 20 II |
| 30 cd/m² | 30 II |
| 40 cd/m² | 40 II |
| 50 cd/m² | 50 II |
| 60 cd/m² | 60 II |
| 70 cd/m² | 70 II |
| 80 cd/m² | 80 II |
| 90 cd/m² | 90 II |
| 100 cd/m² | 100 II |
| 250 cd/m² | 250 II |
| 500 cd/m² | 500 II |
| 750 cd/m² | 750 II |
| 1000 cd/m² | 1,000 II |
| 10000 cd/m² | 10,000 II |
| 100000 cd/m² | 100,000 II |
