সমস্যা সমাধান
Confusing gauge pressure with absolute pressure
সমাধান
This converter uses absolute pressure (measured from zero, i.e., vacuum). Gauge pressure (measured relative to atmospheric pressure) requires adding 1 atm (101.325 kPa) to the reading. Tire pressures are typically gauge pressures.
Using mmHg for barometric pressure when inHg is expected
সমাধান
Aviation altimeters in the US use inHg (e.g., 29.92 inHg). European aviation uses hPa/mbar. Blood pressure readings use mmHg. Always check which unit your instrument or standard requires.
Confusing mbar with mmHg
সমাধান
1 mbar = 0.750 mmHg. They are similar in magnitude but not equal. Millibar is used in meteorology; mmHg is used in medicine and vacuum science.
সচরাচর জিজ্ঞাসিত প্রশ্ন
Which pressure units are supported?
Pascal (Pa), kilopascal (kPa), megapascal (MPa), bar, millibar (mbar), psi, atmosphere (atm), millimeter of mercury (mmHg / Torr), and inch of mercury (inHg).
What is standard atmospheric pressure?
1 standard atmosphere (atm) = 101,325 Pa = 1.01325 bar = 14.696 psi = 760 mmHg = 29.921 inHg. This is the reference pressure at sea level.
What is the difference between bar and psi?
1 bar = 14.504 psi. Bar is the metric unit commonly used in Europe and engineering; psi (pounds per square inch) is the imperial unit commonly used in the US for tire pressure and hydraulics.
What is mmHg used for?
mmHg (millimeters of mercury) is used for blood pressure readings (e.g., 120/80 mmHg), atmospheric pressure in weather science, and vacuum pressure in laboratories.
What is the difference between Pa and kPa?
1 kPa = 1,000 Pa. Pascals are very small units (1 Pa is about the pressure of a dollar bill lying flat). Kilopascals are used for tire pressure, blood pressure in some countries, and weather.
What is Torr?
Torr and mmHg are effectively the same unit (1 Torr = 1 mmHg to very high precision). Torr is often used in vacuum science and high-precision laboratory settings.
What is gauge vs absolute pressure?
Absolute pressure is measured from a perfect vacuum (zero). Gauge pressure is measured relative to atmospheric pressure. Tire pressure gauges show gauge pressure; add 1 atm to get absolute pressure.
