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.
Gram
A gram (g) is a metric unit equal to one-thousandth of a kilogram. It is ideal for measuring lighter items such as spices, medication, small hardware, and jewelry. Because it fits well for everyday small quantities, grams are widely used in cooking, product packaging, and laboratory work.
As part of the metric system, converting grams to kilograms or milligrams is quick and intuitive. But switching between grams and US customary units often requires exact conversion factors, where a converter becomes essential.
