You must make that conversion before you use the ideal gas law. Thus, if you are inserting values of volume into the equation, you first have to convert them into cubic metres.
The major difference will be that the pressure is given in atmospheres or millimetres of mercury or bars or millibars, and volume may be in litres or millilitres. What are the units used for the ideal gas law?
Ernest Z. Dec 25, Step 3: Think about your result. For significant figure purposes, the standard pressure of mmHg has three significant figures. Watch the video to learn more about conversion factors:. Use the link below to practice conversion calculations:. Skip to main content.
States of Matter. Search for:. Pressure Units and Conversions Learning Objectives Be able to convert between different units of pressure. Kilopascal Uses. What is meant by standard pressure? What is the temperature at STP in Kelvin? Is 1 atm a standard pressure? What does kPa stand for in vacuum? What is PV nRT called?
Fifteen Examples. What is STP in physics? What is r in PV nRT? What is the volume of 1 mole of gas at STP? What are the conditions for STP in chemistry?
How do you calculate STP in chemistry? During the Industrial Revolution, the US created its factories, machinery, infrastructure, and most technology around the Imperial System.
To switch to the Metric System would cost thousands and thousands of dollars and take years to switch. This is how the conversion would look:. You have an air compressor that can compress air in a range of about kPa to kPa and you want to know what that range is in psi. What does that equal in kPa? As we said earlier, kPa is the unit usually used in scientific and engineering concepts and applications, as well as in most countries around the world. The kPa unit is used for scientific concepts like physics, engineering, and chemistry in all countries, including the United States.
