1 kilocalorie [thermochemical] = 4.184 × 10¹⁸ femtojoule.
1 femtojoule = 2.390057 × 10⁻¹⁹ kilocalorie [thermochemical].
Multiply the value in kilocalorie [thermochemical] by 4.184 × 10¹⁸ to get the result in femtojoule. Example: 5 kcal × 4.184 × 10¹⁸ = 2.092 × 10¹⁹ fJ.
Kilocalorie [thermochemical] (kcal) is a unit of energy. This is the thermochemical definition of the unit.
1 kilocalorie [thermochemical] = 4,184 joule (J)
1 kilocalorie [thermochemical] = 999.3312 calorie [I.T.] (cal)
1 joule = 0.0002390057 kilocalorie [thermochemical]
The SI prefix kilo- stands for 1,000, so 1 kilocalorie [thermochemical] = 1,000 calorie [I.T.].
Use the converter above to convert kilocalorie [thermochemical] into any other unit of energy.
Femtojoule (fJ) is a unit of energy.
1 femtojoule = 1 × 10⁻¹⁵ joule (J)
1 femtojoule = 2.388459 × 10⁻¹⁶ calorie [I.T.] (cal)
1 joule = 1 × 10¹⁵ femtojoule
The SI prefix femto- stands for 10⁻¹⁵, so 1 femtojoule = 10⁻¹⁵ joule.
