Conversion Definitions


The following is a perform of interpretations relating come conversions in between amps and milliamps.

What is an amp (A)?

An amp (or ampere) is a unit of length in the international System of systems (SI). The symbol for amp is A. There room 0.001 amps in a milliamp.

What is a milliamp (mA)?

A milliamp (or milliampere) is a unit the electric present in the international System of systems (SI). The symbol because that milliamp is mA. There are 1,000 milliamps in one amp.


Conversion Formula


Let"s take a closer look in ~ the counter formula so the you can do these conversions yourself with a calculator or v an old-fashioned pencil and also paper.

The formula to transform from amps come milliamps is:

milliamps = amps x 1,000

Conversion Example


Next, let"s watch at an example showing the work and also calculations that are connected in convert from amps to milliamps (A to mA).

Amp to Milliamp conversion Example

Task: transform 8 amps come milliamps (show work)Formula:amps x 1,000 = milliampsCalculations:8 amps x 1,000 = 8,000 milliampsResult:8 amps is equal to 8,000 milliamps
For rapid reference purposes, below is a switch table that you have the right to use to convert from amps come milliamps.
