7. Dimensions and units¶
Below is a table showing the dimensions and its associated units in AGX Dynamics. Where possible, SI units are being used. Many of the units are derived from the gravitational acceleration \(g\). It has a default value in AGX Dynamics of 9.80665 m/s2 and can be found in agx/Math.h.
