How to Turn Foot Candles to Lumens
- 1). Look up the number of foot-candles emitted by your light-source product in the manufacturer's specifications. Say it's a bulb emitting 100 foot-candles.
- 2). Divide that number by 0.929, which is the conversion factor.
- 3). Arrive at your answer in lumens per-square-meter. In our example 100 / 0.929 = 1,076.4.
