Illuminance is the total luminous flux incident on a surface per unit area. It is measured in lux (lx).
1 lm/m² = 0 ph
1 ph = 10,000 lm/m²
Example:
Convert 15 Lumens per Square Meter to Phot:
15 lm/m² = 0.002 ph
| Lumens per Square Meter | Phot |
|---|---|
| 0.01 lm/m² | 1.0000e-6 ph |
| 0.1 lm/m² | 1.0000e-5 ph |
| 1 lm/m² | 0 ph |
| 2 lm/m² | 0 ph |
| 3 lm/m² | 0 ph |
| 5 lm/m² | 0.001 ph |
| 10 lm/m² | 0.001 ph |
| 20 lm/m² | 0.002 ph |
| 30 lm/m² | 0.003 ph |
| 40 lm/m² | 0.004 ph |
| 50 lm/m² | 0.005 ph |
| 60 lm/m² | 0.006 ph |
| 70 lm/m² | 0.007 ph |
| 80 lm/m² | 0.008 ph |
| 90 lm/m² | 0.009 ph |
| 100 lm/m² | 0.01 ph |
| 250 lm/m² | 0.025 ph |
| 500 lm/m² | 0.05 ph |

| 1000 lm/m² | 0.1 ph |
| 10000 lm/m² | 1 ph |
| 100000 lm/m² | 10 ph |
