## 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 is Exapascal?

What is Exapascal Unit of Measure? Exapascal is a multiple of pressure unit pascal. One exapascal is equal to 10000 gigabars.

**How do you convert units to other units?**

Summary

- Write the conversion as a fraction (that equals one)
- Multiply it out (leaving all units in the answer)
- Cancel any units that are both top and bottom.

### 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.

### Where is mmHg from?

Millimeters of Mercury at a temperature of zero degrees Celsius is a small metric pressure unit which is derived from the hydrostatic pressure generated by a 1 mm tall column of mercury liquid.

**What are 5 common units of pressure and their conversions?**

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.

**Is 760 torr an exact number?**

The torr (symbol: Torr) is a unit of pressure based on an absolute scale, defined as exactly 1760 of a standard atmosphere (101325 Pa). Thus one torr is exactly 101325760 pascals (≈ 133.32 Pa)….
