The IFGC protects public health and safety for all building systems that use fuel gas for the design, installation and inspection of such systems by providing minimum safeguards for people at homes, schools and workplace. Fuel burning appliances, furnaces, chimneys, vents, gas pipe sizing and many other such issues are addressed in the IFGC.

Since 1982, STP has been defined as a temperature of 273.15 K (0 °C, 32 °F) and an absolute pressure of exactly 1 bar (100 kPa, 10 5 Pa). NIST uses a temperature of 20 °C (293.15 K, 68 °F) and an absolute pressure of 1 atm (14.696 psi, 101.325 kPa). [3] This standard is also called normal temperature and pressure (abbreviated as NTP).
However, the pressures can easily be converted into SI units, e.g. kilopascals, where 1 psi = 6.8947573 kPa or, roughly, one psi equals seven kPa. Additional notes A note on Gnuplot SVG terminal: Set size variable as "fixed" (the default in Gnuplot), not "dynamic", to ensure correct aspect ratio.
Uncertainties of several degrees should generally be assumed. (e) Indicates extrapolated values beyond the region of experimental data, subject to greater uncertainty. (i) Indicates values calculated from ideal gas thermodynamic functions. (s) Indicates the substance is solid at this temperature. As quoted from these sources:
In petroleum geology and the petrochemical sciences pertaining to oil wells, and more specifically within hydrostatics, pressure gradients refer to the gradient of vertical pressure in a column of fluid within a wellbore and are generally expressed in pounds per square inch per foot (psi/ft). This column of fluid is subject to the compound ...
The pascal (Pa) or kilopascal (kPa) as a unit of pressure measurement is widely used throughout the world and has largely replaced the pounds per square inch (psi) unit, except in some countries that still use the imperial measurement system or the US customary system, including the United States.
