This webpage Is all about measurement using the metric system.
Types of measurements and their definitions
Length - distance from one point to another
Mass - amount of matter in an object
Volume - amount of space an object occupies
Density - amount of matter in and amount of space (how tightly packed)
Temperature - average kinetic energy (energy of motion) in an object
Different Base Units and their abbreviations in the Metric system are
Length - Meters (m)
Mass - Grams (g)
Volume - Liters (L) or Cubic Centimeters (cm3)
Density - Grams divided by cubic centimeters (g/cm3)
Temperature - Kelvin (K)
Common unit prefixes, their meanings, and their abbreviations
Mega - 1,000,000 base units (M)
Kilo - 1,000 base units (k)
Hecto - 100 base units (h)
Deka - 10 base units (da)
Deci - 0.1 base units (d)
Centi - 0.01 base units (c)
Milli - 0.001 base units (m)
Micro - 0.000 001 base units (µ)
Nano - 0.000 000 001 base units (n)
Pico - 0.000 000 000 001 base units (p)
To find out how many base units are in a derived unit, multiply the amount of derived units by the number above. To find out how many grams are in 435 cg you would multiply it by 0.01 to get 4.35 g. This works for every type of measurement.
