How to convert energy in calories (cal) to joules (J).
A small calorie is the energy required to raise 1 gram of water by 1°C at a pressure of 1 atmosphere.
Large Calorie (cal) is the energy required to raise 1 kg of water by 1 degree Celsius at a pressure of 1 atmosphere.
Large calorie is also called food calorie and is used as a unit of food energy.
1 calth = 4.184 J
The energy in joules E(J) is equal to 4.184 times the energy in thermochemical calories E(calth):
E(J) = 4.184 × E(calth)
1 calth = 4.184 J
Convert 300 calth to joules.
E(J) = 4.184 × 300calth = 1255.2 J
2 calth = 8.368 J
Convert 300 calth to joules.
E(J) = 8.368 × 300calth = 2.510.4 J
5 calth = 20.92 J
Convert 300 calth to joules.
E(J) = 20.92 × 300calth = 6.276 J
1 cal15 = 4.1855 J
The energy in joules E(J) is equal to 4.1855 times the energy in 15°C calories E(cal15):
E(J) = 4.1855 × E(cal15)
1 cal15 = 4.1855 J
Convert 300 cal15 to joules.
E(J) = 4.1855 × 300cal15 = 1255.65 J
2 cal15 = 8.371 J
Convert 300 cal15 to joules.
E(J) = 8.371 × 300cal15 = 2511.3 J
5 cal15 = 20.9275 J
Convert 300 cal15 to joules.
E(J) = 20.9275 × 300cal15 = 6278.25 J
1 Cal = 4.184 kJ = 4184 J
The energy in joules E(J) is equal to 4184 times the energy in large/food calories E(Cal):
E(J) = 4184 × E(Cal)
1 Cal = 4.184 kJ = 4184 J
Convert 0.3 Cal to joules.
E(J) = 4184 × 0.3 Cal = 1255.2 J
2 Cal = 8.368 kJ = 8.368 J
Convert 0.3 Cal to joules.
E(J) = 8.368 × 0.3 Cal = 2510.4 J
Calories to joules conversion calculator ►
To convert a calorie measurement to a joule measurement, multiply the energy by the conversion ratio.
Since one calorie is equal to 4.184 joules, you can use this simple formula to convert:
joule = calorie × 4.184
Energy in joules is equal to 4.184 times a calorie.
For example, here's how to convert 5 calories to joules using the formula above.
5 cal = (5 × 4.184) = 20.92 J
Both calorie and joule are units used to measure energy. Keep reading to learn more about each unit of measurement.
calories
One calorie is equal to the amount of heat required to raise the temperature of one gram of water from 14.5 to 15.5 °C.
When measuring the energy content of foods, the larger calorie or kilocalorie is used, but it is often referred to simply as "the calorie". It is common to refer to a calorie as a "small calorie" when both calorie and large calorie are used in the same context.
Calorie can be abbreviated as Cal; For example, 1 calorie can be written as 1 calorie.
joule
A joule is energy equal to the force exerted on an object of one newton at a distance of one meter. [1] One joule is equal to the heat energy dissipated by a current of one ampere through one ohm of resistance in one second.
One joule is also equal to the energy required to move an electric charge of one coulomb through a potential difference of one volt. Furthermore, one joule is also equal to one watt-second.
The joule is the SI derived unit for energy in the metric system. Joule can be abbreviated as J; For example, 1 joule can be written as 1 J.
