Tips & Best Practices

Temperature conversions are special — they're not simple multiplication (unlike length or weight). Always double-check: 100°C = 212°F, 0°C = 32°F.
For cooking: 1 cup = 240 mL, 1 tablespoon = 15 mL, 1 teaspoon = 5 mL.
For running: 1 mile = 1.609 km. A 5km run = 3.11 miles.
Data storage: 1 GB = 1,024 MB (binary), though manufacturers often use 1 GB = 1,000 MB (decimal).
For weight loss tracking: 1 pound = 0.4536 kg. 5 lbs = 2.27 kg.
