About Rounding and Fractions

This calculator is designed for everyday use, not for scientific or laboratory purposes. To make results easier to read and use in daily life, we apply the following simplifications:

• Decimal rounding: Results are rounded to 3 significant digits, which is more than enough for cooking, shipping, or personal weight tracking.
• Fraction approximations: When we display fractions (like "2 1/2 lb"), we only show them if the approximation error is less than 10%. This ensures the fraction is reasonably close to the actual value.
• The ≈ symbol: We use "≈" (approximately equal) instead of "=" to remind you that these are rounded values.

For high-precision scientific calculations, please use specialized tools or the exact conversion factor: 1 kg = 2.20462262185 lb.
