Illuminance is the total luminous flux incident on a surface per unit area. It is measured in lux (lx).
1 fc·h = 1 lm/m²
1 lm/m² = 1 fc·h
Example:
Convert 15 Footcandle Hour to Lumens per Square Meter:
15 fc·h = 15 lm/m²
| Footcandle Hour | Lumens per Square Meter |
|---|---|
| 0.01 fc·h | 0.01 lm/m² |
| 0.1 fc·h | 0.1 lm/m² |
| 1 fc·h | 1 lm/m² |
| 2 fc·h | 2 lm/m² |
| 3 fc·h | 3 lm/m² |
| 5 fc·h | 5 lm/m² |
| 10 fc·h | 10 lm/m² |
| 20 fc·h | 20 lm/m² |
| 30 fc·h | 30 lm/m² |
| 40 fc·h | 40 lm/m² |
| 50 fc·h | 50 lm/m² |
| 60 fc·h | 60 lm/m² |
| 70 fc·h | 70 lm/m² |
| 80 fc·h | 80 lm/m² |
| 90 fc·h | 90 lm/m² |
| 100 fc·h | 100 lm/m² |
| 250 fc·h | 250 lm/m² |
| 500 fc·h | 500 lm/m² |
| 750 fc·h | 750 lm/m² |
| 1000 fc·h | 1,000 lm/m² |
| 10000 fc·h | 10,000 lm/m² |
| 100000 fc·h | 100,000 lm/m² |
