1 btu = 1055.05585 joules
1 joule = 0.00094781712 btu
3,000 Btu/lb (3,000 British thermal unit/pound)
The official (SI) unit for energy is the joule.
If any other units are used, the value will be different. --Depending on the units you chose the value of the constant differs
1 scf = 1 standard cubic foot 1 scf is the volume of gas at STP STP = Standard Temperature and Pressure STP (USA system of units) Standard Temperature = 60 degrees Fahrenheit Standard Pressure = 1 atmosphere at sea level = 14.696 pounds per square inch absolute The energy content of 1 scf natural gas = 1020 BTU (British Thermal Units)
Because it's a relative value.
A unit of heating value equivalent to 100,000 British Thermal Units (BTUs).
A therm is a unit of measurement used to quantify heat energy. It is equal to 100,000 British Thermal Units (BTUs) and is often used in the context of natural gas consumption or heating systems.
The most popular two heat energy units are: Calorie and BTU (British Thermal Unit).Both these units are obsolete. These days, allforms of energy are measured in joules.
BTU (British Thermal Unit).
3,000 Btu/lb (3,000 British thermal unit/pound)
Joule-Thompson coefficient for methane

thermistors change value as thermal units increases or decreases . that can be used to shut down items that unnecessarily overheat
It is the amount of heat produced by the complete combustion of a unit weight of fuel. Usually expressed in calories per gram or BTU's (British Thermal Units) per pound, the latter being numerically 1.8 times the former.
The official (SI) unit for energy is the joule.
The resistance, the precision of that value, the thermal or electrical environment, the style of indicating these values. There are wire-wound resistors, cracked carbon resistors, carbon resistors and so on.
The R value of a material is the thermal resistance of the material, so is dependent on the material's thickness. R is also the inverse of a material's thermal conductivity U. To work it out you need the k value ( the thermal conductivity) of the material and the thickness, then R=thickness/k. The k value for structural concrete (of density 2300kg/m3) is 1.6 W/mK (Units: Watts / (metre x degrees Kelvin) so for a thickness 100mm (0.1m) of this concrete, R=0.06 m2°C/W. Note that the R value in imperial units will not be the same. Check the units for any R value of any material that is given.
