ISO to DIN degrees
Type a value in ISO to get it in °DIN instantly.
27.02°DIN
That's about the same as general-purpose film. That is 2 stops from ISO 100.
Convert the other way: °DIN to ISO
What it means
How sensitive is that?
Digital cameras quote an ISO-equivalent sensitivity. Above the base ISO the sensor is not more sensitive, only amplified — which is where the noise comes from.
The math
How to convert ISO to °DIN
DIN is logarithmic and ISO is not: DIN = 10 × log₁₀(ISO) + 1, so every doubling of ISO adds three DIN degrees.
Example: 400 ISO = 27.0206 °DIN.
