No other base units have a prefix, so why does mass?

Alright! Think of the SI unit like a special ruler for measuring stuff. A long time ago, when scientists were picking the best size for the ruler’s main mark for weight, they thought a gram was too tiny. So, they chose the kilogram because it was a better size for lots of things they measured. Just like sometimes we use feet instead of inches for bigger distances. So, the kilogram became the main mark on our weight ruler!
