MKS system of units

The MKS system of units is a way of measuring things so that everyone in the world uses the same numbers to describe them.

Imagine you have a toy car and you want to know how fast it can go. You could say it goes 5 feet per second, but your friend who lives in another country might say it goes 2 meters per second. This is confusing because one person is using feet and the other is using meters!

So scientists and mathematicians created the MKS system to make sure everyone is using the same units. MKS stands for "meter-kilogram-second" which means the system uses the meter as a unit for length, the kilogram as a unit for weight, and the second as a unit for time.

For example, if you want to measure how tall someone is, you would use meters. If you want to measure how heavy something is, you would use kilograms. And if you want to measure how long it takes for something to happen, you would use seconds.

Using the same units makes it easier for scientists, engineers, and other people who work with numbers to communicate with each other and solve problems.
