Calorific value

	J/m3
	them/ft3
	kJ/m3
	kcal/m3
	Btu/ft3
	Chu/ft3
	MJ/m3

1 kcal/m³ standard, saturated) = 1.0171 kcal/m³(standard, dry)

1 kcal/m³ standard, dry) = 1.0548 kcal/m³(normal, dry)

1 MJ/m³ = 1 J/cm³

Wobbe index = GCV / √ Specific Gravity 

Specific Gravity = (density of gas / density of air) at standard conditions

Density of air (0°C, 1 atm) = 1.2928 g/L or kg/m³
