How to convert from calories to joules

Thermochemical calories to joules

1 calth = 4.184 J

So The energy in joules E(J) is equal to 4.184 times the energy in thermochemical calories E(calth).

E(J) = 4.184 × E(calth)

Example 1

Convert 700 calth to joules.

E(J) = 4.184 × 700calth = 2928.8 J

Example 2

Convert 900 calth to joules.

E(J) = 4.184 × 900calth = 3765.6 J

Example 3

Convert 2000 calth to joules.

E(J) = 4.184 × 2000calth = 8368 J

15°C calories to joules

1 cal15 = 4.1855 J

So The energy in joules E(J) is equal to 4.1855 times the energy in 15°C calories E(cal15).

E(J) = 4.1855 × E(cal15)

Example 1

Convert 700 cal15 to joules.

E(J) = 4.1855 × 700cal15 = 2929.85 J

Example 2

Convert 900 cal15 to joules.

E(J) = 4.1855 × 900cal15 = 3766.95 J

Example 3

Convert 2000 cal15 to joules.

E(J) = 4.1855 × 2000cal15 = 8371 J

Large/food calories to joules

1 Cal = 4.184 kJ = 4184 J

So The energy in joules E(J) is equal to 4184 times the energy in large/food calories E(Cal).

E(J) = 4184 × E(Cal)

Example 1

Convert 0.5 Cal to joules.

E(J) = 4184 × 0.5 Cal = 2092 J

Example 2

Convert 1.5 Cal to joules.

E(J) = 4184 × 1.5 Cal = 6276 J

Example 3

Convert 2.3 Cal to joules.

E(J) = 4184 × 2.3 Cal = 9623.2 J
