Conversion Definitions
The complying with is a perform of meanings relating come conversions between milliamps and also amps.
What is a milliamp (mA)?
A milliamp (or milliampere) is a unit of electric current in the international System of devices (SI). The symbol because that milliamp is mA. There are 1,000 milliamps in one amp.
What is an amp (A)?
An amp (or ampere) is a unit of length in the worldwide System of systems (SI). The symbol because that amp is A. There room 0.001 amps in a milliamp.
Conversion Formula
Let"s take a closer look at the counter formula so the you can do this conversions yourself through a calculator or with an old-fashioned pencil and paper.
The formula to transform from milliamps to amps is:
amps = milliamps ÷ 1,000
Conversion Example
Next, let"s look at an example showing the work and also calculations that are affiliated in converting from milliamps to amps (mA to A).
Milliamp come Amp conversion Example
Task: transform 1,500 milliamps to amps (show work)Formula:milliamps ÷ 1,000 = ampsCalculations:1,500 milliamps ÷ 1,000 = 1.5 ampsResult:1,500 milliamps is equal to 1.5 amps
For quick reference purposes, listed below is a switch table that you have the right to use to transform from milliamps come amps.
