Pressure Conversion

Pressure is expressed as force exerted over an area. It can be measured using several scales with the most popular units of measurement:

• millibars (mb)
• atmospheres (atm)
• millimeters of mercury (torr)

Pressure is defined as force per unit area. Use this Formula Solver to learn how to convert between pressure’s primary units of measurement — millibars, atmospheres, and millimeters of Mercury (or torr).

When converting pressure from millibars, use these conversion rates:

• 1 torr = 1.33322 millibars
• 1 atm = 1013.25 millibars

When converting pressure from atmospheres, use these conversion rates:

• 1 torr = 0.00131579 atmospheres
• 1 mb = 0.000986923 atmospheres

When converting pressure from torr, use these conversion rates:

• 1 mb = 0.75 torr
• 1 atm = 760 torr
