Understanding the Units: Milligrams and Grams
What is a Milligram?
A milligram (mg) is a unit of mass in the metric system. It is one-thousandth of a gram, making it a very small measurement typically used for substances such as medications, supplements, or small quantities of chemicals. To put it into perspective:
- 1 milligram = 0.001 grams
What is a Gram?
A gram (g) is a basic unit of mass in the metric system. It is widely used in cooking, science, and everyday measurements. For example:
- A standard paperclip weighs about 1 gram.
- A teaspoon of sugar weighs roughly 4 grams.
