InputMeaning and units
Reference-format diagonal (mm)Enter reference-format diagonal in mm; use the same basis as the other measurements.
Sensor diagonal (mm)Enter sensor diagonal in mm; use the same basis as the other measurements.

Understanding your result

Read Crop factor (1) in the units and model stated on this page. The formula crop=reference/sensor defines the relationship; measurement accuracy and model applicability are separate from numerical precision.

Common mistakes

  • Mixing input units or changing the physical meaning of a variable without changing the model.

Check your calculation

  • Use the worked example as a known reference case, then change one input at a time and check the direction and units of the response.
