pylupnt.UnitSystem

class pylupnt.UnitSystem

Length/time/mass scale factors defining a working unit system.

acceleration_from_si(self: pylupnt._pylupnt.UnitSystem, arg0: SupportsFloat | SupportsIndex) → float

Convert an acceleration [m/s^2] into this unit system.

area_from_si(self: pylupnt._pylupnt.UnitSystem, arg0: SupportsFloat | SupportsIndex) → float

Convert an area [m^2] into this unit system.

area_per_mass_from_si(self: pylupnt._pylupnt.UnitSystem, arg0: SupportsFloat | SupportsIndex) → float

Convert an area-per-mass [m^2/kg] into this unit system.

from_si(self: pylupnt._pylupnt.UnitSystem, value: SupportsFloat | SupportsIndex, length_power: SupportsInt | SupportsIndex, time_power: SupportsInt | SupportsIndex = 0, mass_power: SupportsInt | SupportsIndex = 0) → float

Convert an SI value into this unit system given length/time/mass dimensional powers.

gm_from_si(self: pylupnt._pylupnt.UnitSystem, arg0: SupportsFloat | SupportsIndex) → float

Convert a gravitational parameter [m^3/s^2] into this unit system.

property length

Length unit as a multiple of the SI meter.

length_from_si(self: pylupnt._pylupnt.UnitSystem, arg0: SupportsFloat | SupportsIndex) → float

Convert a length [m] into this unit system.

property mass

Mass unit as a multiple of the SI kilogram.

pressure_from_si(self: pylupnt._pylupnt.UnitSystem, arg0: SupportsFloat | SupportsIndex) → float

Convert a pressure [Pa] into this unit system.

property time

Time unit as a multiple of the SI second.

to_si(self: pylupnt._pylupnt.UnitSystem, value: SupportsFloat | SupportsIndex, length_power: SupportsInt | SupportsIndex, time_power: SupportsInt | SupportsIndex = 0, mass_power: SupportsInt | SupportsIndex = 0) → float

Convert a value in this unit system back to SI (inverse of from_si).

velocity_from_si(self: pylupnt._pylupnt.UnitSystem, arg0: SupportsFloat | SupportsIndex) → float

Convert a velocity [m/s] into this unit system.
