Tips for Accurate Conversions

  • Double-Check Results: Verify conversions, especially for critical measurements
  • Understand Precision: Be aware of rounding - converters show appropriate decimal places
  • Use Appropriate Units: Choose units that make sense for your use case
  • Consider Context: Some conversions are approximate (e.g., fluid ounces vs weight ounces)
  • Save Common Conversions: Bookmark frequently used converters for quick access

Understanding Conversion Accuracy

Our converters use precise conversion factors with up to 6 decimal places of accuracy. Temperature conversions use scientific formulas, ensuring accuracy suitable for:

  • Everyday use and general calculations
  • Educational purposes and homework
  • Most professional applications
  • Scientific and engineering work (with appropriate precision awareness)

Special Considerations

Important Notes

  • Temperature: Uses precise formulas - Celsius to Fahrenheit: (C × 9/5) + 32
  • Volume: Be aware of US vs Imperial gallons (different sizes)
  • Weight: Distinguish between avoirdupois and troy ounces when relevant
  • Time: Months vary in length - conversions use average month length
