- Batch Conversion : Convert lists of values
- Formula Display : Show conversion formulas
Quick Start
from unit_converter import UnitConverter
converter = UnitConverter()
# Simple conversion
result = converter.convert(100, "km", "miles")
print(f"100 km = {result:.2f} miles")
# With full details
result = converter.convert_with_details(72, "fahrenheit", "celsius")
print(result)
CLI Usage

Example Workflows
Batch Conversion
converter = UnitConverter()
weights_kg = [50, 75, 100, 125]
weights_lbs = converter.batch_convert(weights_kg, "kg", "lbs")
for kg, lbs in zip(weights_kg, weights_lbs):
print(f"{kg} kg = {lbs:.1f} lbs")
Find Compatible Units
converter = UnitConverter()
# Search for units
matches = converter.find_unit("meter")
# Returns: ['meter', 'kilometer', 'centimeter', ...]
Get Conversion Formula
converter = UnitConverter()
formula = converter.get_formula("celsius", "fahrenheit")
print(formula) # "F = (C × 9/5) + 32"
Output Format
convert_with_details()
{
"value": 100,
"from_unit": "km",
"to_unit": "miles",
"result": 62.1371,
"formula": "miles = km × 0.621371",
"category": "length"
}
