METRIC CONVERSIONS
1 X 10-6 M-u = 0.001 K-u = 1 unit = 100 c-u = 1000 m-u = 1 x 106 µ-u
Smaller so there’s more
Bigger so there’s less
Try this with money: $1, a quarter, $10, a penny, $100
$1 = 4 quarters
$1 = 100 pennies
$1 = .1 of $10
$1 = .01 of $100
u = unit such as meter, gram or liter
M=mega
K=kilo
c=centi
m=milli
µ = micro
Any equality (ex. 1 unit = 100 c-u) can be used as a conversion factor:
1𝑚
100 𝑐𝑚
or
100 𝑐𝑚
1𝑚
Because the two values are equal (there are 100 cm in 1 m), we can use these to convert from one unit to another in a process
known as dimensional analysis.
75.4 cm = ? m
1𝑚
75.4 cm x 100 𝑐𝑚 = 0.754 m The cm units are divided out and the answer is in meters.
Can you explain this?
1 cm = 10 mm so 1 cm3 = 1000 mm3
