# How do you convert 1.05 atm of pressure to its equivalent in millimeters of mercury?

##### 2 Answers

#### Explanation:

The method of doing this conversion depends on what specific information we have at hand. I'll do the conversion two different ways to show what I mean. This answer has the direct version, and the next will have a two-step version.

First, lets assume that we have measurement or reference for atm in terms of mm-Hg. In this case we can look up the value of mm-Hg for 1 atm (Atmosphere (unit) ):

Then we can turn this into a conversion factor:

We can now apply the conversion by starting with the unit we have, and selecting the factor that cancels that unit and leaves the one we want:
