kilo- means "1000".
Examples:
- kilogram is one thousand grams
- kilohertz is one thousand oscillations per second
- kilovolt is one thousand volts
- kilobyte is roughly one thousand bytes of storage (used because 210, or 1024, is the power of two closest to 1000 bytes: it is easily close enough to one thousand, or one kilo-, for describing computer storage in general terms).
