UNIT CONVERSION FACTORS

To convert from units in the left-hand column (A) to units in the right-hand column (B) multiply by thenumber in the middle column. To convert from units in the right-hand column (B) to units in the left-handcolumn (A) divide by the number in the middle column. For example:

Foot 304.80= Millimeter Millimeter 304.80 = Foot

The conversion factors are approximate and for reference use only. Conversion factors have beenrounded to five significant digits.

LENGTHA To convert from A to B, multiply A by:

To convert from B to A, divide B by:B

Foot (ft) 304.80 Millimeter (mm)Foot (ft) 30.480 Centimeter (cm)Foot (ft) 0.30480 Meter (m)Foot (ft) 12.000 Inch (in)Inch (in) 25.400 Millimeter (mm)

PRESSUREA To convert from A to B, multiply A by:


Pound per square inch (psi) 6.8948 Kilopascal (kPa)Pound per square inch (psi) 27.708 Inches water column (60F) (in

H2O, 60F)Pound per square inch (psi) 16.000 Ounce per square inchPound per square inch (psi) 0.068948 Bar

Note:Pressure is usually indicated as gauge pressure, which is the pressure recorded by a pressure gauge and does notinclude the atmospheric pressure. However, most gas property tables use units of absolute pressure; to convert a gaugepressure to absolute pressure the prevailing atmospheric pressure must be added to the gauge pressure.

GAS FLOW RATEA To convert from A to B, multiply A by:


Dec/d (decatherm per day, seenote 2)

1000 scf/d (standard cubic feet per day)

Dec/d (decatherm per day, seenote 2)

28.174 m3/d (standard cubic metersper day)

mcf/d (thousand standard cubicfeet per day)



0.028174 e3m3/d (thousand standardcubic meters per day)



mmcf/d (million standard cubicfeet per day)

1 000 000 scf/d (standard cubic feet per day)

scf/d (standard cubic feet per day)


scfm (standard cubic feet per minute)


Notes:1. The standard gas reference temperature and pressure used for US customary units and SI units are not exactly the same.

Therefore, conversion factors for gas volumes used above do not corresponded to those used for ordinary volumes.

2. A decatherm (also spelled dekatherm) is technically a unit of energy, not volume. One decatherm is approximately1000000 BTU. However the decatherm is sometimes used to express natural gas volumes based on its heating value, for this table a heating value of 1000 BTU/scf was used.

GAS HEATING VALUEA To convert from A to B, multiply A by:


MJ/m3 (mega Joule per cubicmeter)

26.704 BTU/scf (British Thermal Unitper standard cubic foot)

Note:The standard gas reference temperature and pressure used for US customary units and SI units are not exactly the same.Therefore, the conversion factors for gas volumes incorporated in the factors above do not corresponded to those usedfor ordinary volumes.
