Milliamp Conversion: A Comprehensive Guide for Beginners

Understanding Milliamps

Milliamp (mA) is a unit of measurement for electric current, representing one-thousandth of an ampere (A). It plays a crucial role in various electronic devices, including smartphones, laptops, and medical equipment.

Conversion Formulas

Milliamps to Amps:

mA ÷ 1000 = A

Amps to Milliamps:

A × 1000 = mA

Applications of Milliamps

Electronics:
- Powering small devices such as sensors, LEDs, and transistors
- Measuring circuit current in low-power applications

Medical:
- Monitoring heart rate and blood pressure in medical devices
