Web21 dec. 2024 · Fact 3: Hg Can Be Measured in 2 Different Ways The first way to measure Hg is known as the Hg gauge (HgV). The scale goes from 0" Hg (atmospheric pressure) to 29.92" Hg (perfect vacuum). The second way to measure Hg is the Hg absolute (HgA). This measurement is the reverse of the Hg gauge. WebPSIG is also known as Gauge Pressure. The ambient pressure at sea level is about 14.7 PSIA, but ambient PSIG is always 0. Taking that into account, our completely empty tire’s PSIG reading would be -14.7. That’s because the gauge measures the pressure inside the tire compared to the atmospheric pressure outside of it.

Web22 mei 2024 · When pressure is measured relative to atmospheric pressure (14.7 psi), it is called gauge pressure (psig). The term gauge pressure is applied when the pressure in the system is greater than the local atmospheric pressure, p atm. The latter pressure scale was developed because almost all pressure gauges register zero when open to the atmosphere.
