Question
A mercury manometer measures a pressure of 200 mmHg. What is this pressure in atm?
Solution
To convert the pressure from mmHg to atm, we need to use the conversion factor that 1 atm is approximately equal to 760 mmHg.
Here are the steps to convert 200 mmHg to atm:
- Identify the given pressure: 200 mmHg.
- Identify the conversion factor: 1 atm = 760 mmHg.
- Set up the conversion so that the unwanted unit will cancel out. You can write this as: (200 mmHg) * (1 atm/760 mmHg).
- Do the math. When you multiply 200 by 1/760, you get approximately 0.263 atm.
So, the pressure of 200 mmHg is approximately equal to 0.263 atm.

You are working with a triple sealed tank with pressure gauges that measure the pressure inside each tank. The gauges report the gauge pressure inside each tank with respect to the pressure in the tank surrounding it. A mercury manometer is connected to the inner most tank, and the other end to the manometer is connected to the atmosphere. All three gauges read -20kPa. What is the reading height of the manometer fluid in mmHg? Please note 1 mmHg = 133.3 Pa)
