the side thingy
How do you find perimeter of a square/rectangle
How many sides a s/r has
area?
length times wiidth
How to change temperature from celcius to ferinheit
x times 1.8 plus 32
how to find the average mass of something
total mass/how many things there are
metric length
meter
metric mass
gram
metric volume
liter/cm3
x + x
2x
x + y =
x + y
3x - 2x =
x
3x - 2y =
3x - 2y
2x times 3x
6xy
4x/2x
2
4x/2y
2x/y
when two different units are multiplied together, they are separated by a
dot
45.01 in scientific notation
4.501 x 10 1
0.00671 in scientific notation
10 -3
length smallest to greatest
micro, milli, centi, dec, Base, Dka, Hec, Km
2 instruments to measure length
tape measurer, meterstick
instruments to measure vol
graduated cylinder, beaker, erlynmeyer flask
base unit for temperature in metric
0C
Why is it important to express units
so you know the meanings of the numbers
when the decimal moves to the left when converting to scientific notation, it is
positive
when the decimal moves to the right when converting to sn, it is
negative
when the exponent is positive when converting to standard n, you move to the
right
when the exponent is negative when converting to standard n, you move to the
left
precision
how consistent the results are when measurements are repated
accuracy
how close a measurement is to the true value
when doing metric unit conversions, don’t forget to put final answer in
scientific notation
when doing area, don’t for get to put _ after your unit
