The equation to find stress is force/area . Stress can be measured as Pascals. I don't know if i should do any convertions. From mm to meters. From Grams to kilograms?

Thank you for your question. Unit agreement is very important when making calculations. A pascal (Pa) is the SI unit for pressure or stress. So force, measured in newtons (N), would be kilogram meters per second per second (kg*m/s^2) and area would be in square meters (m^2). So a pascal would be (kg/(m*s^2)).
So, the short answer is yes...you need to ensure you convert any measurements to these units.
I hope this helps.
