Under intense heat and pressure, the soft coal turns into hard coal.

That's going to depend on-- starting temperature of the water-- finishing temperature of the water-- efficiency of the method you use to heat the water.But we'll play the game.Here are the numbers we're using:Energy content of typical commercial grade natural gas in the US: 1,000 BTU per ft3or 100,000 BTU per ccf.Heat capacity of water: 1 BTU per pound-mass per degree Fahrenheit.Density of water: 8.34 lb/gallon = 0.52125 lb-mass per cupFrom this mash-up, we get(1 cup) x (0.52125 lbm/cup) x (1 BTU/lbm-degree) / (100,000 BTU/ccf) = 0.0000052125 ccf per degree FahrenheitExample: To raise the temperature of 1 cup of water 100 degrees:0.0000052125 x 100 = 0.052125 cubic foot of natural gas, IF all of the energyin the natural gas could be transferred to the water.
Natural gas is methane or CH4. There are 5 atoms in natural gas.
ABOUT 875 BTUs a month, or 6.4 CCF per month
Therms Natural Gas to CCF Natural Gas multiply by 0.9756
1.034 therms
Converting CFH to CCF is hard, and there are several online converters to improve this operation. However, the general rule of thumb for conversion is: 1 Therms (u's) to Cubic Feet Of Natural Gas = 99.9761.

conversion of CCF's to Therms.Example:125 CCF's X 1.024 (therm factor) = 128.0 ThermsMultiply the CCF's by 1.024 and your result is therms.to convert CCF rates to ThermsDivide the CCF price by 1.024 and the result is the therms priceExample,$0.4438/ 1.024 = $.04334...Joe Cityadditional details:CCF : 100 Cubit FeetThermal Factor: The number of Therms per CCF (Therm/CCF).Therm = 100,000 BTU, appx 29.3 KWatt HoursThermal Factors used by fuel companies generally vary between 102% and 103%. These can vary due to fuel quality, temperature, fuel line pressure, etc. Thermal Factor is not a constant. It is (theoretically) calculated by your supplier and provided on your bill as a conversion from your meter reading to the number used for billing.Fuel meters are usually read in an integer format. Therms are generally reported in an integer format, either from round off or round up. If your fuel supplier rounds off your Therms:- below (1+int((1/(Thermal Factor-1)/2)) CCF, you get some gas for free.- from about (1+int((1/(Thermal Factor-1)/2)) CCF to (1+int((1/(Thermal Factor-1))) CCF you pay a little extra.- if you're heating you home in the winter, just extend the pattern.If your fuel supplier just rounds up your Therms ... let's simply say he's ripping you off just a little each month.-- dusc2don
