A milligram, abbreviated as mg, is a tiny unit of mass in the metric system.
It's equal to one-thousandth of a gram (0.001 g). While incredibly small, the milligram plays a massive role in our daily health, from the medicine we take to the food we eat.
The milligram (mg) is a critical unit of measurement for quantifying the active ingredients in medications. Its small size allows for the precise dosage needed to make a drug effective and safe.
Why is dosage in mg so important?
You'll see milligram (mg) dosages clearly listed on standard medications, such as aspirin, ibuprofen, and prescription pills.
When you read a nutrition facts label, you'll see many vitamins and minerals listed in milligrams (mg).
Essential nutrients like Vitamin C, iron, calcium, and sodium are all measured in mg to help you understand your daily intake. For example, the recommended daily allowance of Vitamin C for an adult is around 75-90 mg. Understanding these measurements is key to maintaining a balanced and healthy diet.
It can be difficult to picture just how small a milligram is. Here's a simple way to visualize it:
The name itself gives a clue: it combines the Latin prefix "milli" (meaning "thousandth") with the base unit, gram. This means there are 1,000 milligrams in one gram.
The stone (st) is a unit of measurement equal to 14 pounds (lb).
It's part of the imperial system and is still commonly used in a few countries, especially for weighing people.
For use in international contexts or scientific applications, the stone is often converted to the metric system.
One stone is equal to exactly 6.35029318 kilograms (kg).
This precise conversion is used in international trade and science to ensure everyone is using the exact standard measurement.
Although it's an older unit, the stone remains the primary unit of measurement for body weight in the United Kingdom and Ireland.
It's common to hear someone state their weight as a combination of stone and pounds, like "12 stone 6 pounds."
The stone traces its origins back to the medieval English wool trade, where a "stone of wool" referred to a standard 14-pound measure used for buying and selling.
Stones for other goods could vary in weight—for example, a stone of glass was just 5 pounds—but over time, the 14-pound stone became the official legal standard.
