  • How to Measure Natural Gas

    Quantities of natural gas are usually measured in cubic feet. CRMU lists how much gas residential customers use each month in 100 cubic feet increments or (100 cubic feet – 1 hcf). For example, a typical natural gas futures contract is a financial instrument based on the value of about 10 million cubic feet (Mmcf) of natural gas.
