Illuminance is the total luminous flux incident on a surface per unit area. It is measured in lux (lx).
1 br = 0 lm/cm²
1 lm/cm² = 10,000 br
Example:
Convert 15 Brightness to Lumen per Square Centimeter:
15 br = 0.002 lm/cm²
| Brightness | Lumen per Square Centimeter |
|---|---|
| 0.01 br | 1.0000e-6 lm/cm² |
| 0.1 br | 1.0000e-5 lm/cm² |
| 1 br | 0 lm/cm² |
| 2 br | 0 lm/cm² |
| 3 br | 0 lm/cm² |
| 5 br | 0.001 lm/cm² |
| 10 br | 0.001 lm/cm² |
| 20 br | 0.002 lm/cm² |
| 30 br | 0.003 lm/cm² |
| 40 br | 0.004 lm/cm² |
| 50 br | 0.005 lm/cm² |
| 60 br | 0.006 lm/cm² |
| 70 br | 0.007 lm/cm² |
| 80 br | 0.008 lm/cm² |
| 90 br | 0.009 lm/cm² |
| 100 br | 0.01 lm/cm² |
| 250 br | 0.025 lm/cm² |
| 500 br | 0.05 lm/cm² |
| 750 br | 0.075 lm/cm² |
| 1000 br | 0.1 lm/cm² |
| 10000 br | 1 lm/cm² |
| 100000 br | 10 lm/cm² |
