Metric vs Imperial Systems
The metric system uses base-10 calculations making it easier for scientific work, while imperial units are commonly used in the US for everyday measurements.
Temperature Conversion Formulas
Celsius to Fahrenheit: (°C × 9/5) + 32. Fahrenheit to Celsius: (°F - 32) × 5/9. Kelvin to Celsius: K - 273.15.
Precision Considerations
For scientific work, use maximum precision. For everyday conversions, 2-3 decimal places are usually sufficient. Consider rounding rules for your specific application.
Common Conversion Mistakes
Always verify unit types (mass vs weight), check decimal placement, and be aware of regional variations in unit definitions (US vs Imperial gallons).
