Mass is a fundamental unit of physics with the SI unit as kilograms. but there is a situation when we cannot use kilograms, suppose a situation when we need to measure the weight one a needle, then if we consider kilogram unit. this will be a very unreliable, the results will be very ambiguous, this is the reason for tiny masses measurement we need to use units whose mass equivalent is very small, such two units are grams and milligrams.

## gram to milligram

A gram is a tiny unit of mass, to get the mass of one gram, consider a body with one kilogram of mass and then divide its mass into 1000 equal parts. Take one piece, the mass of this part will be similar to one gram.

one gram is a very small unit, but when we take the division of one gram by 10^3, then we take this as one milligram of the group. Well, one milligram is a tiny unit of mass, this is actually when you make 1000 parts of one gram, well you can now imagine how small a milligram is when we consider measuring mass.

**Here in this section, let’s use an equation and convert grams to milligrams,**

One gram is equal to 10^-3 milligrams; this implies that 10^3 milligrams are required to make a gram of unit. Now if you want to convert 2 grams into milligrams then according to the equation, it will be equal to 2 x 10^3 milligrams

**Precautions while conversion**

- Take care of to use correct equivalent factor, when you are converting units,
- Conversion of units includes multiplication and division; this is very important to pay your full attention.

• Apply necessary units before the value to make conversion look simple
