Current Converter: Convert Between Amps, Milliamps, Microamps, and More

Introduction

Electric current is a fundamental electrical quantity measured in amperes. Our current converter handles all common units.

Conversion Formulas and Factors

The ampere is the SI base unit:

1 mA = 0.001 A 1 �A = 0.000001 A 1 kA = 1000 A 1 A = 1000 mA = 1,000,000 �A

Ohm's Law: I = V / R

How to Use the Converter

Our current converter supports all standard units. For example, 500 mA = 0.5 A.

Real-World Examples

Electronics: An LED draws 20 mA = 0.02 A. Household: A 1500 W heater at 120 V draws 12.5 A = 12,500 mA. Industrial: A large motor draws 200 A = 0.2 kA.

Common Applications

• Electronics Design: Calculating current requirements for components
• Electrical Engineering: Sizing wires, fuses, and breakers
• Battery Technology: Measuring charge rates in mAh
• Automotive: Alternator output and starter current
• Power Systems: Load flow and fault current analysis

Tips for Accurate Conversions

1. 1. Use mA for electronics, A for household, kA for industrial
2. 2. Current ratings on wires are maximum safe values
3. 3. Distinguish between mAh (capacity) and A (instantaneous)
