List of Worldwide AC Voltages and Frequencies

by Ron Kurtus (updated 11 June 2019)

The voltage and frequency of alternating current (AC) electricity used in homes varies from country to country throughout the world. Typically, either 120-volt AC or 240-volt AC is used.

Most countries use 50Hz (50 Hertz or 50 cycles per second) as their AC frequency. Only a handful use 60Hz.

The standard in the United States is 120V and 60Hz AC electricity. However, due to fluctuations, the average measured voltage is 117 VAC.

The voltage and frequency of AC electricity varies from country to country throughout the world. Most use 220V and 50Hz. About 20% of the countries use 110-120 V and/or 60Hz to power their homes. 220-240 V and 60Hz are the most efficient values, but only a few countries use that combination. The United States uses 120V and 60Hz AC electricity.
