BTU

BTU

The BTU is the imperial unit for thermal energy, particularly used in HVAC (heating, ventilation, and air conditioning) systems in North America.

Almindelig

Calorie

cal

The calorie is a unit of thermal energy defined as the heat required to raise 1 gram of water by 1°C. While largely superseded by joules, it remains in some scientific contexts.

Videnskabelig

Electronvolt

eV

The electronvolt is the natural energy scale for atomic and subatomic processes. It's the energy gained by an electron when accelerated through a potential difference of 1 volt.

Videnskabelig

Gigawatt

GW

The gigawatt is a unit of power used to measure the output of large-scale power generation facilities and the consumption of entire electrical grids. One gigawatt is enough to power approximately 700,000 homes.

Almindelig Videnskabelig

Horsepower

hp

The horsepower is an iconic imperial unit for measuring power, defined historically as the power output of a draft horse. It remains standard for car engines in the US and automotive industry worldwide.

Almindelig

Joule

J

The joule is the SI unit of energy, named after English physicist James Prescott Joule. It's the fundamental unit for all energy calculations in physics and engineering.

Videnskabelig

Kilocalorie

kcal

The kilocalorie is the "Calorie" you see on food labels in countries using metric units. In the US, this same unit is called a "Calorie" (capital C), creating confusion between the two terms.

Almindelig Videnskabelig

Kilojoule

kJ

The kilojoule is the practical metric unit for food energy on nutrition labels outside the United States. It's also used for describing thermal energy and power outputs.

Almindelig Videnskabelig

Kilowatt

kW

The kilowatt is the practical unit for measuring moderate to large power levels, from kitchen appliances to electric vehicle charging rates.

Almindelig Videnskabelig

Kilowatt Hour

kWh

The kilowatt hour is the unit you see on your electricity bill. It measures electrical energy consumption and is used by all utility companies globally.

Almindelig Videnskabelig

Megajoule

MJ

The megajoule is used for measuring large quantities of energy in industrial contexts, such as fuel energy content or power plant outputs.

Videnskabelig

Megawatt

MW

The megawatt is used for measuring large power generation and consumption. Power plant capacities, solar farms, and wind turbines are rated in megawatts.

Almindelig Videnskabelig

Therm

thm

The therm is a unit of energy primarily used by natural gas utilities for billing purposes. It represents a practical quantity of energy that makes gas consumption easier to understand on customer bills.

Almindelig

Watt

W

The watt is the SI unit of power named after Scottish engineer James Watt. It's displayed on every electrical device, from light bulbs to appliances and power supplies.

Almindelig Videnskabelig

Watt Hour

Wh

The watt hour is the practical unit for battery capacity and stored electrical energy. It's displayed on battery labels and power banks worldwide.
