What does the prefix kilo mean?

The prefix kilo means one thousand times the base unit.

Kilo tells you to multiply the basic unit by one thousand so if you have one kilogram it is one thousand grams, and if you have one kilometer it is one thousand meters. Think of kilo like a big box that holds one thousand little boxes of the smaller unit inside, so counting by kilos jumps you ahead by one thousand each time. When scientists and engineers use kilo they are just making numbers easier to say and compare without writing lots of zeros. It always scales the unit up by one thousand, never down.

A common mistake is thinking kilo means a vague large amount instead of exactly one thousand, so always remember it is precise and equals one thousand; if you forget, write the full number to check. Another error is confusing kilo with other prefixes like mega or milli, so say the name out loud and match the number of zeros to stay sure; one thousand is three zeros. People sometimes mix units, for example calling a kilogram a thousand kilograms by accident, so read the labels carefully and do the multiplication step slowly to avoid that slip.
