Object field width: 25.6 mm Object field height: 19.2 mm Object field diagonal: 32 mm
W = sensor width / M; H = sensor height / M; diagonal = √(W² + H²)

No. Use the specified or measured magnification at the working distance. Distortion, digital zoom, image-circle coverage and resolution are not evaluated.
Calculations run on your device. Form inputs are not sent to a server.
The initial choice follows your browser region. Your choice is remembered on this device. Gallons are US gallons. Switching units keeps your numbers unchanged and interprets them in the new unit.
Numbers stay unchanged. Check the new unit and enter the intended measurement, or select an example for that system.

Mistake: Changing units and assuming the entered numbers were converted.
Fix: Numbers stay unchanged. Check the new unit and enter the intended measurement, or select an example for that system.
Mistake: Treating a result as valid outside the described scope.
Fix: No. Use the specified or measured magnification at the working distance. Distortion, digital zoom, image-circle coverage and resolution are not evaluated.
