The RD_UCF subroutine returns UCF(Unit correlation factor).
UCF is defined as “UCF * 1.0 [F] = 1.0 [ML/T^2]”.

ucf |
double |
The output variable, The unit of the output of the force type must be used [F] unit. |
NOTE
The units are used [N], [kg], [mm], and [s]. The UCF is always 1000.0. ( 1[N] = 1000 [kg*mm/s^2] )
The unit of the output of the force type USUB functions must be used [F] unit. If user uses the [MLT^-2] force unit, then output force vectors needed to multiply the 1/UCF value.
