I am looking at a pump and it says ultimate pressure is 7.5x10-4 torr whats this work out at in HG? I have looked on the net and cant figure out how to convert it. Thanks!
I don’t know anything about that unit of measure, but:
Here’s a converter http://www.convertworld.com/en/pressure/Torr.html
If you read http://en.wikipedia.org/wiki/Vacuum it looks like it’s a medium amount of vacuum.
1 Torr is equal to 1 mm hg more or less and 25.4 mm is equal to 1 in. Just use those and run through the numbers to get your answer.
In your case it looks lie .000754/25.4 to get in hg
