Units are case-sensitive. Generally only units with useful conversions are defined. Unit tracking or aggregation is generally not desired. If no unit is defined, the default is assumed. The following is a list of standard units.


    • Default is meter. Permissible units are:

        • m

        • mil, mils

        • in, inch

        • ft, foot, feet

        • mi, mile


    • Default is degrees. Permissible units are:

        • deg, degree, degrees

        • rad, radian, radians


    • Default is seconds. Permissible units are:

        • day, dy, days

        • hour, hours, hr, hrs

        • min, minutes, minute

        • s, second, seconds


    • Permissible units are:

        • %


    • Permissible units are:

      • dB: linear translation assumes "voltage" dB, e.g. -3dB is 0.7071 (convention for S-Parameters)


Default is no modifier. If the unit is not one of the above, then the first character in the unit will set the multiplier. Therefore 'nF', 'nH', 'n', and 'no_unit' are all equivalent to Mason (obviously the last one would cause confusing results for the unwary designer).

    • f (1e-15)

    • p (1e-12)

    • n (1e-9)

    • u (1e-6)

    • m (1e-3)

    • c (1e-2)

    • d (1e-1)

    • D (1e1)

    • k (1e3)

    • M (1e6)

    • G (1e9)

    • T (1e12)
