engunits

Typed engineering quantities with SI-default storage, built on pint.

Install

pip install engunits

Quick start

from engunits import Mass, Length, Velocity

# Create quantities — SI units by default
m = Mass(1000, "lb")       # stored internally as kg
l = Length(5, "ft")         # stored internally as m

# Convert on demand
print(m("kg"))              # 453.592 kg
print(l("m"))               # 1.524 m

# Callable syntax for conversion
v = Velocity(100, "m/s")
print(v("ft/s"))            # 328.084 ft/s

# Arithmetic
total = Mass(10, "kg") + Mass(5, "kg")
scaled = Length(3, "m") * 2
ratio = Mass(30, "kg") / Mass(10, "kg")  # returns float: 3.0
