# 400 Mcg Equals How Many Mg?

A milligram is equal to 1,000 mcg, so that means that 400 mcg will be equal to just 4 mg. Mcg stands for a microgram, and mg stands for a milligram. These measurements are incredible small, and are hence only used in particular fields. Cooking and baking generally use grams, whilst larger operations will include measurements like kilograms or tons.

Milligrams and micrograms are generally used in the field of medicine, and are used to specify the amount of a substance that is required in things like tablets, that are used to help people recover from conditions that are treatable.

In the metric system, a microgram is a unit of mass that is equal to just one millionth of a gram. It is one of the smallest units of mass, or weight, that is commonly used. The abbreviation, µg, conforms to the International System of Units and is often used in scientific literature. The JCAHO, based in the United States, instead recommends that hospitals don’t use the abbreviation in handwritten orders given that is can be misread. This simple misunderstanding could cause a thousand-fold overdose in a patient, hence, the abbreviation mcg is recommended for use for the safety of patients.

If you want to type the ‘micro’ symbol, you will need to hold down the Alt key (on a Windows-based computer or program), whilst typing 230 on your keyboard. If you’re using a Mac, you need to hold the Option key whilst you’re pressing ‘m’ on your keyboard. You can also press Alt Gr + M on most keyboards. Using the font face that’s known as simple, Mu is denoted by a lowercase M.

Remember that these measurements are incredibly important in the medical condition, as getting them wrong could actually result in the death of a patient. Getting them right, however, can result in the healing of a patient from a potentially life-threatening disease or condition.

MCG means microgram and MG means milligrams.

1 mg =1000 mcg so that means 400 mcg is equal to .4 mg. You need more than twice of the quantity you have for the medicine.
