Trillion Cubic Feet (Tcf)

Definition - What does Trillion Cubic Feet (Tcf) mean?

Trillion Cubic Feet abbreviated as Tcf is a volume measurement unit of natural gas. A trillion cubic feet (1,000,000,000,000 cubic feet) is equivalent to approximately one Quad. A Quad is an abbreviation for a quadrillion (1,000,000,000,000,000) Btu's. A Btu (British thermal unit) is a unit of measurement for energy, representing the amount of heat that is needed to raise the temperature of one pound of water by one degree Fahrenheit.

Petropedia explains Trillion Cubic Feet (Tcf)

The volume of natural gas is either measured in Billion cubic feet (Bcf) or Trillion cubic feet (Tcf). During custody transfer of natural gas between two parties, the price paid by one party however, does not depend on the volume of natural gas transferred in Tcf. It depends on the enthalpy or the amount of heat or energy the natural gas being traded will generate when it is burnt, i.e., the price or the market value of natural gas depends on the British Thermal Units (Btu).

  • 1 cubic foot (cf) = 1,027 Btu
  • 100 cubic feet (1 hcf) = 1 therm (approximate)
  • 1,000 cubic feet (1 Mcf) = 1,027,000 Btu
  • (1 MMBtu) 1,000 cubic feet (1 Mcf) = 1 dekatherm (10 therms)
  • 1 million (1,000,000) cubic feet (1 Mmcf) = 1,027,000,000 Btu
  • 1 billion (1,000,000,000 cubic feet (1 bcf) = 1.027 trillion Btu
  • 1 trillion (1,000,000,000,000) cubic feet (1Tcf) = 1.027 quadrillion Btu
