Kilowatt-hours to Gigaelectronvolts (kWh to GeV)

1 kilowatt-hour equals 2.246943267×10¹⁶ gigaelectronvolts (rounded).

1 kilowatt-hour = 2.246943267×10¹⁶ gigaelectronvolts

How to convert kilowatt-hours to gigaelectronvolts

To convert kilowatt-hours to gigaelectronvolts, multiply the number of kilowatt-hours by 2.246943267×10¹⁶. The factor is rounded to 10 significant digits. To go the other way, multiply gigaelectronvolts by 4.45049065×10⁻¹⁷.

gigaelectronvolts = kilowatt-hours × 2.246943267×10¹⁶

Example: 10 kilowatt-hours = 2.246943267×10¹⁷ gigaelectronvolts.

The 'calorie' on food labels is really a kilocalorie. The thermochemical calorie (4.184 J) is used here unless marked IT.

About these units

Kilowatt-hour (kWh)

Metric (SI)Current unit

3.6 million joules, the energy used by a 1,000-watt appliance in an hour. The billing unit for household electricity.

Before it was a line on every power bill, the kilowatt-hour had a British nickname: the Board of Trade unit, abbreviated B.T.U. after the government body that regulated the electricity industry until 1942, when the Ministry of Power took over. In India it is still often called simply a unit, and a million of them, written MU, is a gigawatt-hour.

A kilowatt-hour is the energy of a 1 kW device running for an hour, which is 3.6 MJ, or about 3,412 British thermal units. A 100 W television watched for 10 hours uses one, and boiling a liter of water in an electric kettle takes about 0.1. In 2020 the average US household used 893 kWh a month, an average continuous draw of about 1.22 kW.

Utilities multiply the kilowatt-hours consumed by a price per kWh, and larger customers may also pay for peak demand. One common error is writing kW/h, which would mean kilowatts per hour, a rate of change of power, not energy.

1 kilowatt-hour = 3,600,000 joules (exactly).

Gigaelectronvolt (GeV)

ScientificCurrent unit

One billion electronvolts. The scale of particle accelerators; the proton mass is about 0.938 GeV/c².

Accelerators brought this unit into use. Older documents wrote BeV for billion electronvolts, and the Bevatron at Berkeley, which began operating in 1954 and reached a maximum of 13 GeV, took its name from the idea. Creating antiprotons there needed a proton beam of about 6.2 GeV, and the antiproton was found in 1955. The modern symbol GeV equals 1.602176634 x 10^-10 J.

Masses of heavy particles are quoted in GeV/c squared. A proton is about 0.938 GeV/c squared, and the Higgs boson, announced on 4 July 2012 at CERN, has a mass near 125 GeV, about 133 times the proton. At the Large Hadron Collider each proton beam reached 6.5 TeV in 2015, which is 6,500 GeV. The step above is the TeV, a thousand GeV, so the GeV sits in the middle of the energy range of high-energy physics.

1 gigaelectronvolt = 1.602176634×10⁻¹⁰ joules (exactly).
