Conversion Formula
Ohm's Law (relates V, I, R — requires knowing two to find the third): V = I × R • I = V ÷ R • R = V ÷ I Power relationships: P = V × I • P = I² × R • P = V² ÷ R This converter handles within-quantity conversions (V↔mV↔kV, W↔kW↔MW, etc.). Cross-quantity conversions (e.g., watts to volts) require a third known value.

Frequently Asked Questions
How do I convert Milliamp to Ampere?
Multiply your Milliamp value by 0.001 to get Ampere. For example: 10 mA × 0.001 = 0.01 A. You can also use the converter above for instant results.
How many Ampere are in 1 Milliamp?
There are 0.001 A in exactly 1 mA. This is the direct conversion factor between these two units.
Is Milliamp larger or smaller than Ampere?
One Milliamp is smaller than one Ampere. Specifically, 1 mA = 0.001 A, so your number decreases when converting from mA to A.
When would I use Ampere instead of Milliamp?
Use A whenever the context, specification, or audience you are working with uses that unit as the standard.
