If you want to convert up the ladder of metric units (one step at a time), what do you do with the decimal point?
move it to the left
If you want to convert down the ladder of metric units (one step at a time), what do you do with the decimal point?
move it the right
when converting btw temperatures, how many sf should you have
same as the og #
F-C equation
-32/1.8
C-F equation
*1.8 +32
What does the exponent in scientific notation tell you?
how many zeros there are
In dimensional anaylsis, where should your given measurement (measurement that you are converting to another unit) be?
numerator of first box
How do you know when you have the end-result unit in dimensional analysis?
all other units are cancelled (ends up at top as 1 unit)
For dimensional anaylsis, what do you need to do once you plugged in all the numbers in the grid correctly?
multiply all the top numbers, separately multiply all the bottom numbers, then divide product of top numbers by product of bottom numers
If the given measurement has (unit per unit), what does that mean in terms of our grid layout for the first box?
numerator of the first box will be the unit before “per”, denominator of the first box will be the unit after “per”
If the given measurement has (unit per unit), what does that mean in terms of our grid layout for when we finished conversion for one unit and now need the other?
the unit of the denominator of the first box will cancel by putting the same unit as a numerator in a box, followed by its equivalent unit in the denominator
what are the two areas of the metric system that don’t follow the ladder rule?
what is the conversion factor instead of 10? how many places do you move
