Understanding the Units

What is a Torr?

One torr equals exactly 1/760 of a standard atmosphere, or about 133.322 pascals — close to one millimeter of mercury.

Named after Evangelista Torricelli (1608–1647), inventor of the barometer.

Common contexts: vacuum technology, medical blood pressure.

What is a Pascal?

The pascal is the SI derived unit of pressure, equal to one newton of force per square meter (1 Pa = 1 N/m²).

Named after Blaise Pascal (1623–1662), the French mathematician and physicist whose experiments characterized atmospheric pressure.

Common contexts: fluid mechanics, meteorology.

FAQ

How many pascals are in one torr?

One torr equals approximately 133.322 pascals. This is nearly the same as one millimeter of mercury (mmHg).

How do I convert torr to pascals?

Multiply the torr value by 133.322. For example, 760 torr × 133.322 = 101,325 Pa (1 atmosphere).

Is torr the same as mmHg?

Very nearly. One torr is defined as 1/760 of a standard atmosphere, while 1 mmHg is defined by the density of mercury. They differ by less than 0.000015%, so they are used interchangeably.

What vacuum level do common processes need?

Rough vacuum is 760-25 torr, medium vacuum 25-0.001 torr, high vacuum below 10^-3 torr, and ultra-high vacuum below 10^-9 torr.

How many pascals are in 1 torr?

1 torr equals 133.322 Pa.

How do you convert torr to pascals?

Multiply the torr value by 133.322. Formula: Pa = torr × 133.322.

How many pascals are in 5 torr?

5 torr = 666.61 Pa.

How do you convert pascals back to torr?

Use the inverse formula: torr = Pa ÷ 133.322. For example, 1 Pa = 0.007501 torr.

What is the difference between Torr and Pascal?

One torr equals exactly 1/760 of a standard atmosphere, or about 133.322 pascals — close to one millimeter of mercury. The pascal is the SI derived unit of pressure, equal to one newton of force per square meter (1 Pa = 1 N/m²).
