As per the original setting of an UTM system, I applied a default test speed of 0.1 kN/m/min during compression test of a geomaterials. Generally, the loading device follows either a displacement control mode (unit=m/min) or a pressure control mode (unit=kN/m2/min or MPa/min). Please how can I compute the actual loading rate as per standard units i.e m/min or MPa/min
