Exposure value to lux
Type a value in EV to get it in lx instantly.
10,240lx
That's about the same as an overcast day. That is about 4,096 times the light of EV 0.
Convert the other way: lx to EV
What it means
How much light is that?
All values are at ISO 100. Shutter speeds assume f/5.6 and apertures assume 1/60 s, since EV fixes only the combination, not either one alone.
The math
How to convert EV to lx
Exposure value is logarithmic: EV = log₂(N² ÷ t) for aperture N and shutter time t, and each step of one either doubles or halves the light. Lux follows as lux = 2.5 × 2^EV at ISO 100.
Example: 12 EV = 10,240 lx.
