Function Reference

pressure_conversion(value: float, from_unit: str, to_unit: str) -> float

Converts a pressure value between units: pascal, kilopascal, megapascal, bar, psi, atm.

Arguments:

• value (float): The pressure value to convert.
• from_unit (str): The unit of the input value.
• to_unit (str): The desired output unit.

Returns:

• float: Pressure in the desired unit.

---

pascal_to_inches_of_mercury(pascals: float) -> float

Converts Pascals to inches of mercury.

Arguments:

• pascals (float): Pressure in Pascals.

Returns:

• float: Pressure in inches of mercury.

---

convert_fraction(fraction: str) -> float

Converts an imperial fraction (e.g., "1 1/2", "3/4") to a float (in inches).

Arguments:

• fraction (str): The fraction to convert ("1 1/2", "3/4", or "2").

Returns:

• float: Value in inches.

---

imperial_fraction_to_mm(diameter_fraction: str, thickness_fraction: str) -> tuple[float, float]

Converts diameter and thickness from imperial fractions to millimeters.

Arguments:

• diameter_fraction (str): Diameter as an imperial fraction.
• thickness_fraction (str): Thickness as an imperial fraction.

Returns:

• tuple (float, float): (diameter_mm, thickness_mm)

Example Usage

from unitasker import (
    pressure_conversion,
    pascal_to_inches_of_mercury,
    convert_fraction,
    imperial_fraction_to_mm,
)

# Pressure conversion
pressure_psi = pressure_conversion(101325, 'pascal', 'psi')
print(f"Pressure: {pressure_psi:.2f} psi")

# Pascals to inches of mercury
pressure_inHg = pascal_to_inches_of_mercury(101325)
print(f"Pressure: {pressure_inHg:.2f} inHg")

# Imperial fraction to mm
diameter = "1 3/8"
thickness = "3/8"
diameter_mm, thickness_mm = imperial_fraction_to_mm(diameter, thickness)
print(f"Diameter: {diameter_mm:.2f} mm")
print(f"Thickness: {thickness_mm:.2f} mm")
