Formula of converting food/ thermochemical kilocalories to joules

E (J) = 4184 x E (kcal-th), where the energy in joules is computed by multiplying the energy in kilocalories by 4184.

It can also be expressed as;

1 kcal-th = 4184 J.

For example;
Find the energy in joules if the energy in kilocalories is 0.478.

Solution
E (J) = 4184 x E (kcal-th)

= 4184 x 0.478 kcal-th = 1999.952 joules (J)

Converting international kilocalories to joules

E (J) = 4186.8 x E (kcal-IT), which means that the energy in joules is calculated by multiplying the energy in international kilocalories by 4186.8

For example;
If the energy in international kilocalories is 0.478, find the energy in joules.

Solution
E (J) = 4186.8 x E (kcal-IT)

= 4186.8 x 0.478 kcal-IT = 2001.2904 joules (J)

Converting 15° C calories to joules

E (J) 4185.5 x E (kcal15), which means that the energy in joules is computed by multiplying the energy in 15° C calories by 4185.8

For example;
If the energy in 15° C calories is 0.478, find the energy in joules

Solution
E (J) 4185.5 x E (kcal15)

= 4185.5 x 0.478 kcal15 = 2000.669 joules (J)

Converting 20° C calories to joules

E (J) = 4182 x E (kcal20), which means that the energy in joules is calculated by multiplying the energy in 20° C calories by 4182.

For example;
If the energy in 20° C calories is 0.478, find the energy in joules

Solution
E (J) = 4182 x E (kcal20)

= 4182 x 0.478 kcal20 = 1998.996 joules (J)
