Energy
Convert joule (J) to calorie (cal). Energy is the capacity to do work or transfer heat — the currency of every heat and material balance.
1 J = 0.2390057 cal
To convert joule to calorie, multiply the J value by 0.2390057. To go the other way, divide by 0.2390057 (or multiply by 4.184).
| J | cal |
|---|---|
| 1 | 0.2390057 |
| 2 | 0.4780115 |
| 5 | 1.195029 |
| 10 | 2.390057 |
| 25 | 5.975143 |
| 50 | 11.95029 |
| 100 | 23.90057 |
| 250 | 59.75143 |
| 500 | 119.5029 |
| 1000 | 239.0057 |
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 3600000 J is 860420.7 cal.
Multiply the value in J by 0.2390057 to get cal. For example, 10 J = 2.390057 cal.
1 J equals 0.2390057 cal.
