Recommended approach: Store height and length limits in centimetres and weight limits in kilograms.
Check before launch: A height range such as 10 to 20 centimetres is not suitable for human height. Use limits that match the product and audience.
Normalize without confusing the customer
A shopper can enter height in centimetres or feet and inches. Aura converts that input to a canonical centimetre value for validation and production records while preserving a readable display value.
| Question | Metric | Imperial | Canonical storage |
|---|---|---|---|
| Height | cm | ft + in | cm |
| Weight | kg | lb | kg |
| Body length | cm | in | cm |
| Age | years | years | years |
Use production-aware ranges
Minimum and maximum values are validation boundaries, not suggestions. Choose them from the actual product fit envelope and test boundary values in every enabled unit system.
Common questions
Does switching units change the underlying measurement?
No. Aura converts the same canonical value and updates the displayed fields and summary.
