Kilogram
A kilogram (kg) is the primary unit of mass in the metric system and is used worldwide for science, commerce, and everyday life. One kilogram equals 1,000 grams and is commonly seen on product packaging, body weight scales, and nutritional labels. Since the kilogram is the base unit for metric mass, it is straightforward to convert to other metric units.
Kilograms provide a practical scale for most objects we handle daily — from groceries to luggage. When converting between kilograms and US units like pounds and ounces, a converter ensures accuracy without memorizing conversion factors.
Milligram
A milligram (mg) is a very small metric unit of mass equal to one-thousandth of a gram. It is commonly used in medicine, nutrition, and science to measure tiny quantities where precision is crucial. Vitamins, pharmaceuticals, and food additives often list dosage amounts in milligrams because even a small difference can matter.
Milligrams help prevent rounding errors when grams would be too large of a unit. While metric conversions are simple — 1,000 milligrams in a gram — switching to ounces or pounds requires careful calculation, making a converter especially useful.
