Tips for accurate conversions
- Square and cube the factors for area and volume: 1 m = 3.2808 ft, but 1 m² = 10.764 ft².
- Check which “cup”, “gallon” or “ton” is meant. US and UK versions differ.
- Currency rates move every day. The rate your bank charges includes a margin over the mid-market rate shown.
- Local land units vary between states. Confirm with land records before buying or selling.
