Mass/Weight in different Units

Michael asked on SolidWorks forums as “How to show weight in Ounces” as this unit is not available under Tools > Document Properties > Units.  If you also looking for similar thing, here is the simple procedure.

  1. Open the part/assembly file or create a new one and add the bodies/parts as required.
  2. No click on Tools > Equation.
  3. Equation Editor will pop up.
  4. Click on Add.
  5. Next you’ll see is “Add Equation” window.
  6. You can also do the above steps by right click on Equation folder and  selecting “Add Equation”.
  7. Write the equation name. I have used “Mass in Oz”
  8. Now type or click on =
  9. Next is expand the equation editor. Click on the two arrow button on the right bottom corner.
  10. Next you’ll see the list of global variables and file properties (with the values)
  11. Click once on SW-Mass (make sure you click only once).
  12. SW-Mass will appear in equation box.
  13. Now type or click on * (for multiplication).
  14. Now add the conversion factor.  As we are converting from grams to Oz, the conversion factor is 1 gram = 0.0352739619 ounces. Depending on the precision, you can change the value. I’ll use 0.0353.
  15. Click on OK to apply the equation.
  16. You can see the evaluated value.
  17. Click OK to exit equation editor.
  18. Now open File properties. Click on Properties under file menu.
  19. You can add the property under Custom/Config Tab.
  20. Add “Weight” as Property name. Set type as “text“. And for value/ text expression, expand the list and select “Mass for Oz“.
  21. Click OK to apply the changes and exit.
  22. Weight will be shown in Oz units (value) where ever linked.
  23. Similarly you can use the method for other conversion works also 🙂
