Analog signal scaling calculator
Map physical quantities to voltage or current, in either direction. Check endpoints, gain, offset, clipping, and extrapolation.

ON YOUR DEVICEEnter your inputs and calculate to see the result.
Set both endpoints.
This two-point linear calibration works for voltage and current signals, including reversed sensor characteristics. Select how out-of-range inputs are handled. Gain is in electrical units per physical unit; use the same units for both endpoints and your input.
gain = (electrical max − electrical min) / (physical max − physical min)
electrical = gain × physical + offset
