Changing units in the SOLIDWORKS user interface could not be simpler. Go to Tools>Options>Document Properties>Units to change the units that are being used within the SOLIDWORKS design environment. There is also the units' popup menu in the bottom right-hand corner of the SOLIDWORKS screen. Changing units within the SOLIDWORKS Simulation environment is a little more involved but still simple.
SOLIDWORKS Simulation Units can be changed in three ways:
There is only one way to get to the SOLIDWORKS Simulation Default Options; click Simulation>Options>Default Options>Units. From here choose between the SI, English, and Metric unit types. There is also the option to customize units even further by clicking on the drop-down options next to Length/Displacement, Temperature, Angular velocity, and Pressure/Stress. Each unit type has its specific customizable units drop-down menu that can be changed while in this menu.

Also within the Default Options tab is the Color Chart. This chart allows us to set a default number format to Scientific, Floating, and General.

The differences between the three Number formats can be seen below.

The units of some features in SOLIDWORKS Simulation can be changed individually. For example, if you apply a force load to your simulation you can click on the drop-down menu next to the ruler icon where you can choose from SI, English, or Metric units. This is very convenient if you have a force input in SI units but you want to see the force load in English units. All you need to do is enter the units when the feature is set to SI, then switch to English and SOLIDWORKS Simulation will convert the SI units to English just like that.

SOLIDWORKS Simulation allows us to change units used in the simulation for each result plot like in the Stress plot example below. To open a plot right click on the correct plot in the “Results” folder and then click on the “Edit Definition” option. Click on the second drop-down menu in the Display section of the Stress plot. Here there are five unit options to choose from: pascal, pounds per inch square, kilograms-force per centimeter square, megapascals, and kilo-pound per inch square.
To change the unit format in a single result plot go to the “Chart Options” tab under the “Position/Format” section and click on the drop-down indicated in the screenshot below. The decimal places shown on the screenshot below can also be increased or decreased in this section.
