Tips

1. Quick Mental Math: Remember that 1 inch is about 2.5 cm, 1 meter is about 3.3 feet, and 1 mile is about 1.6 km for rough estimates.
2. Choose the Right Unit: Use smaller units (mm, cm, inches) for precise measurements and larger units (km, miles) for distances.
3. Verify Your Results: Check that conversions make sense - kilometers should always be smaller numbers than miles for the same distance.
4. Use Reference Points: Think of familiar objects (a credit card is ~85mm, a door is ~2m tall) to understand scale.
5. Round Appropriately: For most practical purposes, 1-2 decimal places is sufficient unless you need engineering precision.
