Metric Prefixes (review)

Prefix Prefix Symbol Multiplier

mega- M 106 (1000000)

kilo- k 103 (1000)

BASE UNIT - 100 (1)

centi- c 10-2 (0.01)

milli- m 10-3 (0.001)

micro- μ 10-6 (0.000001)

Metric Prefixes (review)

Prefix Prefix Symbol Multiplier

mega- M (unit) = 106 (base units)

kilo- k (unit) = 103 (base units)

BASE UNIT - 100 (1)

centi- c (unit) = 10-2 (base units)

milli- m (unit) = 10-3 (base units)

micro- μ (unit) = 10-6 (base units)

Prefixes and Base Units (review) (any prefix can go with a base unit)Prefixes M (Mega-) k (kilo-) c (centi-) m (milli-) μ (micro-)

Base Units m (meter) g (gram) s (second) L (liter) N (Newton) J (Joule)

Domino Metric Conversions (step #4 - review)For metric dominoes:

The “multiplier” goes with the BASE unit, And “1” goes with the PREFIX unit
