How do you convert between pressure units?
1 atm = 101,325 Pascals = 760 mm Hg = 760 torr = 14.7 psi. The prefix “kilo” means “1,000”, so one kilopascal = 1,000 Pa. Therefore, 101.325 kPa = 1 atm = 760 torr and 100 kPa = 1 bar = 750 torr. The prefix “mega” means “1,000,000”, so one megapascal = 1,000 kPa = 1,000,000 Pa = 9.869 atm = 145 psi.
What are 5 units of pressure?
The SI unit for pressure is pascals (Pa). Other units of pressure include torr, barr, atm, at, ba, psi, and manometric units like mm Hg and fsw.
What is an MPa in pressure?
The megapascal is a x1000000 multiple of the pascal unit which is the SI unit for pressure. 1 megapascal equals 1,000,000 pascals. Primarily used for higher range pressure measurement due to its larger value (e.g. 1 MPa = 10 bar), the MPa is mainly used to describe the pressure ranges and ratings of hydraulic systems.
Is mmHg and torr the same?
The key difference between torr and mmHg is that the value of one torr can be obtained by dividing 101325 from 760, whereas the value of one mmHg is given exactly as 133.3224. While 1 torr equals 0.999 mmHg, I mmHg equals 1.0000004 torr.
Is torr the same as mmHg?
