The gas measurement for methane (natural gas) is measured by volume in cubic feet or cubic metres. One cubic metre of natural gas is the volume of gas enclosed in a cubic metre at standard temperature and pressure. The gas measurement of gas reserves is measured in thousands or millions of cubic metres.
A gas meter is a purpose built flow meter. A gas meter measures the volume of natural gas or LPG – liquified petroleum gas used. Gas meters are used by all gas utilities to measure consumption in homes, industrial and commercial buildings.
The gas unit used in the sale of gas is based on the energy content or calorific value of the gas, not gas volume. The typical gas units for energy content are British Thermal Units - BTU - megajoules (MJ) or therms, not cubic metres or cubic feet.
The distinctive properties of LPG mean that it can be measured in a number of different ways. These include gaseous volume (meter), liquid volume, weight, energy content and pressure. For example, LPG for homes is frequently delivered in 45kg gas bottles.
Gas measurement units (LPG measurement unit) are cubic metres, cubic feet, British Thermal Units (BTU), therms, and PSI as well as litres, kilograms, megajoules (MJ), tonnes and kilopascals (kPa) for gas measurement. The LPG (propane) gas is measured by weight in kilograms, pounds, tons or metric tonnes as gas measurement unit.
LPG gas is measured by weight when sold in gas bottles or cylinders. LPG gas is measured in tonnes when stored or transported in bulk tankers or vessels. LPG gas is measured in litres when it is sold by volume, with correction factors for temperature.
Gas is normally measures at STP - standard temperature and pressure (0°C at 1 atm pressure) or NTP - normal temperature and pressure (20°C at 1 atm pressure). Gas well production is measured in terms of thousands or millions of cubic metres or cubic feet.
Billion cubic metres (billions of m³) is the gas unit for measuring natural gas reserves. In the US, they would use trillion cubic feet (tcf) or billion cubic feet (bcf) as their LPG gas measurement unit. The gas unit for measuring gas well production is in millions of cubic metres (millions m³). These would be, by far, the largest LPG gas measurement units.
