4-20mA Scaling Calculator - Online Tool

Range settings

Lower range (value at 4 mA)

Upper range (value at 20 mA)

Engineering unit

Decimal places (1–6)

Two-way conversion

Current (mA) → process value

Process value: --

Process value → current (mA)

Current: --

Note: 4–20 mA maps linearly to the configured range; a current below 3.6 mA or above 21 mA is flagged asloop failure (shown in red).

Batch conversion

One current value (mA) per line
