What is 220 Kilocalories in Therms?

220 Kilocalories = 0.00873 Therms

How to convert 220 Kilocalories to Therms

To convert 220 Kilocalories to Therms you have to multiply 220 by 3.9666137026405E-5, since 1 Kilocalorie is 3.9666137026405E-5 Therms. The result is the following:

220 kcal × 3.9666137026405E-5 = 0.00873 thm

220 kcal = 0.00873 thm

We conclude that two hundred twenty Kilocalories is equivalent to zero point zero zero eight seven three Therms:

220 Kilocalories is equal to 0.00873 Therms.

Therefore, if you want to calculate how many Therms are in 220 Kilocalories you can do so by using the conversion formula above.

Definition of units

Let's see how both units in this conversion are defined, in this case Kilocalories and Therms:

Kilocalorie (kcal)

Calories are units of energy. Various definitions exist but fall into two broad categories. The first, the small calorie, or gram calorie (symbol: cal), is defined as the approximate amount of energy needed to raise the temperature of one gram of water by one degree Celsius at a pressure of one atmosphere. The second is the large calorie or kilogram calorie (symbol: Cal), also known as the food calorie and similar names, is defined in terms of the kilogram rather than the gram. It is equal to 1000 small calories or 1 kilocalorie (symbol: kcal). Although these units relate to the metric system, all of them have been considered obsolete in science since the adoption of the SI system. The unit of energy in the International System of Units is the joule. One small calorie is approximately 4.2 joules (so one large calorie is about 4.2 kilojoules). The factor used to convert calories to joules at a given temperature is numerically equivalent to the specific heat capacity of water expressed in joules per kelvin per gram or per kilogram. The precise conversion factor depends on the definition adopted.

Therm (thm)

The therm (symbol thm) is a non-SI unit of heat energy equal to 100,000 British thermal units (Btu). It is approximately the energy equivalent of burning 100 cubic feet (2.83 cubic metres) – often referred to as 1 CCF – of natural gas. Since natural gas meters measure volume and not energy content, a therm factor is used by natural gas companies to convert the volume of gas used to its heat equivalent, and thus calculate the actual energy use. The therm factor is usually expressed in units of therms per CCF. It will vary with the mix of hydrocarbons in the natural gas. Natural gas with a higher than average concentration of ethane, propane or butane will have a higher therm factor. Impurities, such as carbon dioxide or nitrogen, lower the therm factor. The volume of the gas is calculated as if measured at standard temperature and pressure (STP). The heat content of natural gas is solely dependent on the composition of the gas, and is independent of temperature and pressure. One therm is equal to about 105.5 megajoules, 25,200 kilocalories or 29.3 kilowatt-hours. One therm can also be provided by about 96.7 cubic feet (2.74 m3) of natural gas. The therm sometimes has been confused with the thermie (see below). The names of both units come from the Greek word for heat.
