MMBTU stands for Million British Thermal Units. Gas consumption in Pakistan is measured in MMBTU. It appears on your gas bill as the monthly consumption figure.

How is Pakistan gas bill calculated?

Pakistan gas bills use a progressive slab system. Lower MMBTU consumption is cheaper per unit. As your usage crosses each slab threshold, only the units in that band are charged at that band's rate — similar to income tax.
