About Calorie
The small calorie (cal) is 4.184 J in this converter (thermochemical). Do not confuse with the dietary kilocalorie (kcal).
About Million BTU (MMBtu, IT)
MMBtu means one million IT BTU: 1,000,000 × 1,055.05585262 J. It is widely used in gas and thermal energy markets.
How to convert calories to million btu (mmbtu, it)
1 calorie is equal to 3.96566683e-9 million btu (mmbtu, it) when both are expressed in joule-equivalents:
1 cal = (4.184 J ÷ 1,055,055,852.62 J) mmbtu = 3.96566683e-9 mmbtu
Each calorie is defined as 4.184 J and each million btu (mmbtu, it) as 1,055,055,852.62 J in this tool, so one cal equals 4.184 ÷ 1,055,055,852.62 mmbtu = 3.96566683e-9 mmbtu.
Let d(cal) be the numeric amount in Calorie (cal), and d(mmbtu) the amount in Million BTU (MMBtu, IT) (mmbtu). Then:
d(mmbtu) = d(cal) × (4.184 / 1,055,055,852.62)
Equivalently, divide by how many cal fit into one mmbtu (joules per mmbtu divided by joules per cal):
d(mmbtu) = d(cal) ÷ 2.52164401e+8
Or: million btu (mmbtu, it) = calorie ÷ 2.52164401e+8
Examples
Example #1: Convert 1 cal to million btu (mmbtu, it)
1 cal = 1 cal × (4.184/1,055,055,852.62) mmbtu = 0.000000004 mmbtu
1 cal = 1 cal ÷ 2.52164401e+8 = 0.000000004 mmbtu
Example #2: Convert 10 cal to million btu (mmbtu, it)
10 cal = 10 cal × (4.184/1,055,055,852.62) mmbtu = 0.0000000397 mmbtu
10 cal = 10 cal ÷ 2.52164401e+8 = 0.0000000397 mmbtu
Summary
To convert Calorie to Million BTU (MMBtu, IT), multiply the value in cal by the ratio of joules per cal divided by joules per mmbtu. Equivalently: value_mmbtu = value_cal × (4.184 / 1055055852.62). Numerically, 1 cal equals 3.96566683139092e-9 mmbtu.
Relationship context
You are converting between food / nutrition energy (calories) (Calories) and US / imperial engineering units (BTU, therm, ft·lb) (Million BTU (MMBtu, IT)). All values are mapped through joules first. The numeric factor is 3.965667e-9.
