Unit Conversion

Functions that convert between units

Each function should accept a single float as an argument and return a single float

Used by the GUI to display values in different units. Widgets use these as

• _convert_in functions to convert units from the base unit to the displayed unit and

• _convert_out functions to convert units from the displayed unit to the base unit.

Note

Unit conversions are cosmetic – values are always kept as the base unit internally (ie. cmH2O for pressure) and all that is changed is the displayed value in the GUI.

Functions:

cmH2O_to_hPa(pressure)	Convert cmH2O to hPa
hPa_to_cmH2O(pressure)	Convert hPa to cmH2O
rounded_string(value[, decimals])	Create a rounded string of a number that doesnt have trailing .0 when decimals = 0

pvp.common.unit_conversion.cmH2O_to_hPa(pressure: float) → float

Convert cmH2O to hPa

Parameters

pressure (float) – Pressure in cmH2O

Returns

Pressure in hPa (pressure*98.0665)

Return type

float

pvp.common.unit_conversion.hPa_to_cmH2O(pressure: float) → float

Convert hPa to cmH2O

Parameters

pressure (float) – Pressure in hPa

Returns

Pressure in cmH2O (pressure/98.0665)

Return type

float

pvp.common.unit_conversion.rounded_string(value: float, decimals: int = 0) → str

Create a rounded string of a number that doesnt have trailing .0 when decimals = 0

Parameters

• value (float) – Value to stringify

• decimals (int) – Number of decimal places to round to

Returns

Clean rounded string version of number

Return type

str
