AngularSpeed¶

class AngularSpeed(value: float | int, unit: str)¶

Bases: UnitBase

AngularSpeed object.

Attributes¶

unitstr: Symbol of the unit of measurement for angular speed.
valuefloat or int: Angular speed numerical value.

Methods¶

to(): It converts actual value to a new value computed using target_unit as the reference unit of measurement.

to(target_unit: str, inplace: bool = False) → AngularSpeed¶

It converts actual value to a new value computed using target_unit as the reference unit of measurement.

If inplace is True, it overrides actual value and unit, otherwise it returns a new instance with the converted value and the target_unit as unit.

Parameters¶

target_unitstr: Target unit to which convert the current value.
inplacebool, optional: Whether to override the current instance value. Default is False, so it does not override the current value.

Returns¶

AngularSpeed: Converted angular speed.

Raises

TypeError

If target_unit is not a str,
if inplace is not a bool.

KeyError

If the target_unit is not among available ones.

Examples

AngularSpeed instantiation.

>>> from gearpy.units import AngularSpeed
>>> s = AngularSpeed(1000, 'rpm')
>>> s
1000 rpm

Conversion from revolutions per minute to radian per second with inplace=False by default, so it does not override the current value.

>>> s.to('rad/s')
104.71975511965977 rad/s
>>> s
1000 rpm

Conversion from revolutions per minute to revolutions per second with inplace=True, in order to override the current value.

>>> s.to('rps', inplace=True)
16.666666666666664 rps
>>> s
16.666666666666664 rps

property unit: str¶

Symbol of the unit of measurement for angular speed. It must be a str. Available units are:

'rad/s' for radian per second,
'rad/min' for radian per minute,
'rad/h' for radian per hour,
'deg/s' for degree per second,
'deg/min' for degree per minute,
'deg/h' for degree per hour,
'rps' for revolutions per second,
'rpm' for revolutions per minute,
'rph' for revolutions per hour.

Returns¶

str: Symbol of the unit of measurement for angular speed.

Raises

TypeError: If unit is not a str.
KeyError: If the unit is not among available ones.

property value: float | int¶

Angular speed numerical value. The relative unit is expressed by the unit property.

Returns¶

float or int: Angular speed numerical value.

Raises

TypeError: If value is not a float or an int.
