Technical Details
Conversions are performed using a base-unit approach: the input value is first converted to grams (the base unit) and then converted from grams to the target unit. The conversion factors are: 1 kg = 1000 g, 1 mg = 0.001 g, 1 lb = 453.59237 g, 1 oz = 28.349523125 g. These are the exact factors defined by the International System of Units (SI) and the avoirdupois system. All calculations use JavaScript floating-point arithmetic and run entirely in your browser with no external API calls.
Conclusion
