What is Microgram?

The microgram is one-millionth of a gram, or one-thousandth of a milligram. Its symbol µg uses the Greek letter mu, denoting the SI prefix "micro." It is commonly used to express recommended daily intakes of vitamins such as vitamin D and vitamin B12. In clinical medicine, hormone levels and certain blood markers are reported in micrograms. Environmental regulations also use micrograms per liter or per cubic meter to set limits on pollutant concentrations in water and air.

What is Kilogram?

The kilogram is the base unit of mass in the International System of Units (SI). Originally defined by a physical platinum-iridium prototype created in 1889, it was redefined in 2019 using the Planck constant for greater precision. It is used worldwide in everyday life, from grocery shopping to scientific research. When you step on a bathroom scale or check a food label, the measurement is typically in kilograms.
