I just took a premium year subscription.
But I see US-units (inch, LBS etc.) is default.
In the Netherlands (EU) we use the SI-system (m, s, kg).
Where on the site can I set SI-system as defualt?
Most calculators are unit less unless otherwise indicated.
The units are suggested for the Modulus of elasticity: lbs/in^2 or N/m^2.
If using SI units keep N/mm^2 and then mm for the other inputs of the calculator.
Keep units consistent with either SI or imperial.
