Unit Systems

There are three unit systems available: mm / t / s, m / kg / s and in / lb / s. These can be changed in the settings menue in the “General Settings” tab. The corresponding units for Young’s Modulus, force, moment, stress constraint, stress and displacement are listet below

Available Unit Systems	mm / t / s	m / kg / s	in / lb / s
Young' Modulus	MPa	Pa	Psi
Force	N	N	lbf
Moment	Nmm	Nm	lbf in
Stress	MPa	Pa	Psi
Displacement	mm	m	in

The corresponding units can be calculated with the conversion factors as follows:

	m / kg / s	mm / t / s	in / lb / s
Length	m	mm	in
Mass	kg	t	lb
Force	N (kg*m)/s²=N	N (tmm)/s²=(0,001kg1000mm)/s²=(kg*m)/s²=N	lbf
Moment	Nm	Nmm	in-lbf
Young’s Modulus, Stress, Pressure	Pa N/m²=Pa	MPa N/mm²=N/(0,001²*m²)=10⁶N/m²=MPa	Psi
Specific Weight	kg/m³	g/mm³	lb/in³
