What dimension sensor is calculated against for the lens equivalent calculator?

All our preset calculations are run against a standard sized full-frame sensor with the dimensions of 36mm x 24mm

My calculations seem different from what I've found in other places.

mmCalc calculates crop factor based on the size of the sensor and rounds it to two decimals places. Most other places typically round the crop factor to one decimal.

Can I request a feature for the site?

Certainly! Just use our contact form. If we like it, we'll add it.

Does mmCalc have an app?

Yup, both iOS and Android.
