1 femtojoule = 9.478171 × 10⁻¹⁹ Btu.
1 Btu = 1.055056 × 10¹⁸ femtojoule.
Multiply the value in femtojoule by 9.478171 × 10⁻¹⁹ to get the result in Btu. Example: 5 fJ × 9.478171 × 10⁻¹⁹ = 4.739085 × 10⁻¹⁸ Btu.
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.
