So, 1 milliampere can be written as 1 mA. What Is a Milliamp?Ī milliampere - often shortened to milliamp - is a submultiple of the ampere equivalent to one thousandth of an ampere (10 -3 A or 0.001 A). Electrical current is a count of the number of charged particles flowing through a conductor.Īmpere is abbreviated A. I made a jump from a 1500 watt amp to a 3500 watt one with new subs and.

Here's how to convert this number to milliamps: 0.46 A × 1000 = 460 mA How many uA in 1 milliampere The answer is 1000. 1 ampere is equal to 1000000 microampere, or 1000 mA. We assume you are converting between microampere and milliampere.You can view more details on each measurement unit: microampere or mA The SI base unit for electric current is the ampere. How many microampere in 1 mA The answer is 1000. My DIY solar phone charger produced a current of 0.46 amps, or 460 milliamps. More information from the unit converter. So, to convert amps to milliamps, just multiply amps times 1000.Ĭonversion formula: milliamps = amps × 1000Ī while back I made my own solar phone charger and used a USB power meter to measure its output. There are 1000 milliamps in 1 amp, just like how there are 1000 millimeters in 1 meter. How to Convert Amps to Milliamps (A to mA) Note: Don't see the values you're looking for in this chart? Use our amps to milliamps conversion calculator at the top of this page to calculate them for your specific scenario. Here is a conversion chart converting common values of amps to milliamps. Convert More information from the unit converter Q: How many Milliamperes in a Ampere The answer is 1,000 Ampere Q: How do you convert 400 Milliampere (mA) to Ampere (A) 400 Milliampere is equal to 0.4 Ampere. Or would you rather convert milliamps to amps?
