+====== Units of Measurement ======
+Visual3D computes all [[Visual3D:Documentation:Visual3D_Signal_Types:LINK_MODEL_BASED_Data_Type|model based items]] using [[https://en.wikipedia.org/wiki/MKS_units|MKS units]], i.e. based on meters, kilograms and seconds. An exception to this rule are [[Visual3D:Documentation:Pipeline:Model_Based_Data_Commands:Joint_Angle#Units_for_Joint_Angles|joint angles]], which are represented in degrees.
+^ Quantity ^ Unit ^
+|Distance | m |
+|Velocity | m/s |
+|Acceleration | m/s/s |
+|Mass | kg |
+|Force | N |
+|Energy | J |
+|Power | W |
+|Moment (Torque) | Nm |
+|Joint Angle | degrees |
+|Joint Angular Velocity | degrees/s |
+|Volume | m cubed |
+===== Analog Units =====
+Visual3D expects certain common [[visual3d:documentation:c3d_signal_types:c3d_format#c3d_parameter_format|parameters]] to be included in the ANALOG Section of the [[visual3d:documentation:c3d_signal_types:c3d_format|C3D file]] when [[visual3d:documentation:c3d_signal_types:analog_data_type|ANALOG]] data is present. If no unit parameter is available for an ANALOG signal then Visual3D defaults to interpreting the signal as being reported in Volts (V).
