It is defined as the amount of work done on a body by a one Newton force that moves the body over a distance of one meter. Wait a minute … is it a unit of energy or a unit of work? Actually, it is a unit of both because the two are interrelated. Energy is just the ability of a body to do work. Anne Marie Helmenstine, Ph.

For example, find watts of power for joules of energy over 40 seconds. You might also like our watts to amps converter for converting power to current. How do you convert joules to MS? The answer is 9. What are the units of Pascals?
The pascal symbol: Pa is the SI derived unit of pressure used to quantify internal pressure, stress, Young's modulus and ultimate tensile strength. The unit, named after Blaise Pascal, is defined as one newton per square metre. The unit of measurement called standard atmosphere atm is defined as Pa.
