Energy
Convert kilojoule (kJ) to calorie (cal). Energy is the capacity to do work or transfer heat — the currency of every heat and material balance.
1 kJ = 239.0057 cal
To convert kilojoule to calorie, multiply the kJ value by 239.0057. To go the other way, divide by 239.0057 (or multiply by 0.004184).
| kJ | cal |
|---|---|
| 1 | 239.0057 |
| 2 | 478.0115 |
| 5 | 1195.029 |
| 10 | 2390.057 |
| 25 | 5975.143 |
| 50 | 11950.29 |
| 100 | 23900.57 |
| 250 | 59751.43 |
| 500 | 119502.9 |
| 1000 | 239005.7 |
Heat duties integrate to energy in kJ, MJ, or BTU; utilities are billed in kWh or MMBTU.
A calorie, a BTU, and a joule are all energy — keep the conversion factors handy when a spec mixes them.
Worked example. A energy of 3600 kJ is 860420.7 cal.
Multiply the value in kJ by 239.0057 to get cal. For example, 10 kJ = 2390.057 cal.
1 kJ equals 239.0057 cal.
