How It Works
Unit conversion is just multiplying and dividing. For example, inches to centimeters is just multiply by 2.54. But remembering all those conversion factors is a pain — this tool saves you the mental math. It has built-in conversion tables for length, weight, temperature, area, volume, speed, and more. You pick a value, it automatically applies the right formula.
Tips & Tricks
- • For temperature, remember: 0°C = 32°F, 100°C = 212°F — it's a linear scale
- • 1 inch ≈ 2.54 cm — memorize this for buying furniture from abroad
- • 1 pound ≈ 0.45 kg — useful for estimating international shipping weights
