Why?

everyone else does

easy to use ( if you grew up with it- based on units of 10) 1m = 10 dm = 100cm = 1000mm x10 x10 x10

Known as SI system systeme internationalePrefixes indicate the multiple of 10 kilo= 1000 x 1000m=1kilometer

deci= 1/10th 1m=10dm centi= 1/100th 1m=100cm

milli= 1/1000th 1m =1000mm

Standards

exact quantity people agree to use for comparison Length- distance between 2 points: meter

Volume- amount of space an object occupies: liter

Mass- amount of matter in an object: kilogram

Time- seconds

Temperature- celsius or kelvin

Derived units

These are units obtained by combining different SI units. example: density- mass/volume so g/mL or Kg/L speed: m/sec or km/hr
