Current Converter

About This Tool

This Current Converter is a fundamental tool for electronics, electrical engineering, and physics. It converts units of electric current, which is the rate of flow of electric charge. The base unit is the ampere (A), one of the seven SI base units.

This tool is essential for circuit analysis, power calculations, and understanding the behavior of electronic components. It covers the modern SI unit (ampere) as well as older units from the CGS system of electromagnetism.

Tips & Features

• The Ampere: The ampere (A), often shortened to 'amp', is the SI base unit of electric current. The 2019 redefinition of SI base units defines it by fixing the elementary charge 'e' to an exact value, and then relating the ampere to the flow of this charge.
• EMU vs. ESU: Older physics texts may refer to units from the electromagnetic (EMU) and electrostatic (ESU) CGS systems. The abampere (or biot) is the EMU unit of current, and the statampere is the ESU unit. They differ significantly in scale.
• Current vs. Charge: Current is the rate of flow of charge (charge per unit time). One ampere is equal to one coulomb of charge flowing per second (1 A = 1 C/s).
