Exposure value to candelas per square meter
Type a value in EV to get it in cd/m² instantly.
512cd/m²
That's about the same as an overcast day. That is about 4,096 times the light of EV 0.
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 cd/m²
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 = 512 cd/m².
