Examples
Recipe scale
8 oz of flour ≈ 226.8 g. US recipes use volume + ounces; metric cooks need grams.
Shipping weight
2.5 kg package ≈ 5.51 lb. Useful when comparing carrier rates priced in different units.
Common use cases
- Cooking with cross-system recipes
- Shipping/parcel weight conversions
- Fitness tracking when scale shows kg but plan uses lb
- Travel: airline luggage allowances in unfamiliar units
Troubleshooting
- Decimal places truncated.
- The display trims trailing zeros for readability. Internally the precision is preserved — copy the value if you need it to feed another calculation.
