Length Converters
Pick a family to convert between defined metric and imperial length units using stable international constants.
Explanation
Each length family follows the official international definitions (1 ft = 0.3048 m, 1 in = 2.54 cm, 1 mi = 1.609344 km). Grouping them keeps the constants transparent while the navigation stays consistent.
How to use this hub
- Choose a converter family.
- If converting to/from grams from a volume unit, select an ingredient.
- For pure unit changes (volume↔volume or weight↔weight), use universal conversions.
If your conversion includes grams, you’ll choose an ingredient; otherwise you won’t.
Frequently Asked Questions
Why are these length conversions grouped?
They share the same international standards so grouping them keeps the constants explicit and the navigation consistent.
Are these ratios exact?
Yes. They rely on the official definitions (1 ft = 0.3048 m, 1 in = 2.54 cm, 1 mi = 1.609344 km) so the factors never change.
How do I flip the direction?
