Installation

pip install pyquantity

Requirements:

• Python 3.10 or higher (following Python's version support policy, mostly)

For Developers:

python test_with_coverage.py

Quick Start

from pyquantity import Quantity, get_measurement, parse_quantity

# Basic quantity operations
length = Quantity(5.0, "meter")
width = Quantity(3.0, "meter")
area = length * width

# Unit conversion
distance = Quantity(1.5, "kilometer")
distance_m = distance.convert("meter")

# Contextual measurements
bath = get_measurement("normal bath")
cup = get_measurement("cup")
cups_in_bath = bath / cup

# Natural language parsing
text = "A car traveling at 120 km/h for 2.5 hours"
quantities = parse_quantity(text)
