Convert Megapascals to Torr

1 megapascal is 7,500.616827 Torr. One megapascal is exactly 7500.61682704 torr.

One megapascal is 7500.6168 torr. To convert megapascals to torr, multiply by 7500.6168; to go the other way, divide by 7500.6168 or multiply by 1.3332 × 10^-4. The factor is exact rather than rounded: it follows from NIST Special Publication 811. A million pascals.

How do you convert megapascals to torr?

  1. 1.Take the measurement in megapascals.
  2. 2.Multiply by 7500.6168 — that is how many torr fit in one megapascal.
  3. 3.To go back the other way, divide by 7500.6168, or multiply by 1.3332 × 10^-4.

Worked example: 25 megapascals to torr

Formula
MPa × 7500.6168 = Torr
Arithmetic
25 × 7500.6168 = 187,515.420676 Torr
Answer
25 MPa = 187,515.420676 Torr

The factor is rounded for display; the figure above is computed from the full value.

What is a megapascal?

A million pascals. Concrete strength and hydraulic ratings are specified here: 30 MPa concrete is about 4,350 psi.

What is a torr?

Exactly one seven-hundred-and-sixtieth of a standard atmosphere. Within a millionth of a millimetre of mercury, which is what it replaced, and still the unit of vacuum work.

How many torr are in a megapascal?

One megapascal is 7500.6168 torr. Going the other way, one torr is 1.3332 × 10^-4 megapascals. Both figures come from the same defined relation rather than from a measurement, which is why they are the same today as they were in 1959.
