	Natural gas is measured in therms or BTUs. A therm is a
	measurement of the amount of heat energy in natural gas, equal to 100,000 BTUs.
	A BTU, or British Thermal Unit, is the quantity of heat required to raise the 
	temperature of one pound of water by one degree Fahrenheit. The current charge
	for natural gas from Peoples Gas 
	is $0.3025 per therm.

	Gas calculator - equation
		
	Cost to operate = usage (hours or load) x (BTUs/100,000) x price per therm
	OR
Cost to Operate = usage (hours or load) x therms x price per therm
