  2. Pound per square inch - Wikipedia

    en.wikipedia.org/wiki/Pound_per_square_inch

    Since atmospheric pressure at sea level is around 14.7 psi (101 kilopascals), this will be added to any pressure reading made in air at sea level. The converse is pound per square inch gauge (psig), indicating that the pressure is relative to atmospheric pressure. For example, a bicycle tire pumped up to 65 psig in a local atmospheric pressure ...

  3. Pressure measurement - Wikipedia

    en.wikipedia.org/wiki/Pressure_measurement

    A pressure gauge reading in psi (red scale) and kPa (black scale) The SI unit for pressure is the pascal (Pa), equal to one newton per square metre (N·m −2 or kg·m −1 ·s −2). This special name for the unit was added in 1971; before that, pressure in SI was expressed in units such as N·m −2. When indicated, the zero reference is ...

  5. Mercury pressure gauge - Wikipedia

    en.wikipedia.org/wiki/Mercury_pressure_gauge

    The parent of all mercury pressure gauges is the mercury barometer invented by Evangelista Torricelli in 1643. [15] An early engineering application of the mercury pressure gauge was to measure pressure in steam boilers during the age of steam. The first use on steam engines was by James Watt while developing the Watt steam engine between 1763 ...

  6. Pressure - Wikipedia

    en.wikipedia.org/wiki/Pressure

    For gases, pressure is sometimes measured not as an absolute pressure, but relative to atmospheric pressure; such measurements are called gauge pressure. An example of this is the air pressure in an automobile tire, which might be said to be "220 kPa (32 psi)", but is actually 220 kPa (32 psi) above atmospheric pressure. Since atmospheric ...

  7. Leak-down tester - Wikipedia

    en.wikipedia.org/wiki/Leak-down_tester

    Most instruments use 100 psi (690 kPa) as the input pressure simply because ordinary 100psi gauges can be used which corresponds to 100% but there is no necessity for that pressure beyond that. Any pressure above 15 psi (100 kPa) will function just as well for measurement purposes although the sound of leaks will not be quite as loud. Besides ...
