Let's learn the core metric prefices for kilo, hecto, deca, deci, centi, and milli

Each prefix is a factor of 10 higher than the one smaller than it. So, for example, kilo is 1000 of the base unit, and centi is one one hundredth of the base unit.

Each prefix has one or two letters that are always used to represent it. Deca has two, to distinguish it from deci.

We add the prefix to the thing being measured, like meters for length or grams for weight. So 1 milligram is written 'm' paired with a 'g', and is one one thousandth of a gram

A simple way to think about these prefices is that they represent powers of 10. This will be useful for very large or very small units.

A good mneumonic to use is 'king henry died by drinking chocolate milk'
