Conversion formula

milligrams (mg) = grams (g) × 1000

How to convert g to mg?

To convert grams (g) to milligrams (mg), multiply the number of grams by 1,000. This is because 1 gram equals 1,000 milligrams.

Example

5 grams × 1,000 = 5,000 milligrams
0.75 grams × 1,000 = 750 milligrams

This straightforward calculation is commonly used in various fields, including science, medicine, and cooking.

1 gram is equal to how many milligrams?

milligrams (mg) = grams (g) × 1000
milligrams (mg) = 1 × 1000
milligrams (mg) = 1000

1 gram = 1000 mg

About Grams

Definition

A gram (symbol: g) is a metric unit of mass equal to one-thousandth of a kilogram. It serves as a fundamental unit in the International System of Units (SI) for measuring mass.

History

The term "gramme" was adopted by the French National Convention in 1795, replacing the earlier unit "gravet." It was initially defined as the mass of one cubic centimeter of water at the temperature of melting ice (0°C). This definition was later refined to specify water at 4°C, its temperature of maximum density. In the 19th century, the gram became the base unit of mass in the centimeter-gram-second (CGS) system of units. However, with the adoption of the International System of Units (SI) in 1960, the kilogram was designated as the base unit of mass, making the gram a derived unit equal to one-thousandth of a kilogram.

Current Use

Today, the gram is widely used worldwide to measure non-liquid ingredients in cooking and grocery shopping. Liquid ingredients are often measured by volume rather than mass. In nutrition labeling, contents are commonly stated per 100 grams of the product, allowing for easy comparison and understanding of nutritional information.
