Illuminance is the total luminous flux incident on a surface per unit area. It is measured in lux (lx).
1 lm/cm² = 1 ph
1 ph = 1 lm/cm²
Example:
Convert 15 Lumen per Square Centimeter to Phot:
15 lm/cm² = 15 ph
| Lumen per Square Centimeter | Phot |
|---|---|
| 0.01 lm/cm² | 0.01 ph |
| 0.1 lm/cm² | 0.1 ph |
| 1 lm/cm² | 1 ph |
| 2 lm/cm² | 2 ph |
| 3 lm/cm² | 3 ph |
| 5 lm/cm² | 5 ph |
| 10 lm/cm² | 10 ph |
| 20 lm/cm² | 20 ph |
| 30 lm/cm² | 30 ph |
| 40 lm/cm² | 40 ph |
| 50 lm/cm² | 50 ph |
| 60 lm/cm² | 60 ph |
| 70 lm/cm² | 70 ph |
| 80 lm/cm² | 80 ph |
| 90 lm/cm² | 90 ph |
| 100 lm/cm² | 100 ph |
| 250 lm/cm² | 250 ph |
| 500 lm/cm² | 500 ph |
| 750 lm/cm² | 750 ph |
| 1000 lm/cm² | 1,000 ph |
| 10000 lm/cm² | 10,000 ph |
| 100000 lm/cm² | 100,000 ph |
