Single Unit Conversions Notes and Practice

2. Single Unit Conversions

3. Conversions
We use conversion factors to tell us what values of measurements are equal.
Conversion factors can be flipped.
Ex: 1min/60 sec = 60 sec / 1min

4. Steps: Draw a horizontal line and an equals sign.
Always start with what you are given on the top left (unit with the number attached)
Write the unit of what you want to convert to after the equals sign
Find the conversion factor that lets you convert between the 2
Chose which side of the conversion factor goes on bottom so the units will cancel
Put the other side of the conversion factor on top
Cancel your units to make sure the only unit left is what you are trying to find
Multiply the top numbers and divide by the bottom numbers.

5. Example:
How many centimeters in 1.59 meters?

6. Examples: How many seconds in 3 minutes? How many feet in 87 inches?
How many ounces in 600 grams?

Multiple Unit Conversions Notes and Practice
UNIT TEST FRIDAY, SEPTEMBER 11, 2015!!!!!!!!!!!!

8. Multiple Unit Conversions
We use double unit conversions when we don’t have a conversion factor that gets us to the desired unit in one step.
Remember: conversion factors can be flipped!

9. Steps: Draw your railroad tracks.
Locate conversion factors that will get you to the desired unit. Write out in a chain what you are going to convert to.
Start with the unit that you have. Put this in the upper left corner of your railroad tracks.
Write the first unit conversion with the unit you start with on the bottom. (So they match!) Cancel the units.
Continue writing unit conversions with the unit of the previous conversion factor on bottom in the next unit conversion until you get to the desired unit.
Multiply the numbers on top and divide the numbers on bottom.
Include the unit in your answer.

10. Example:
How many ounces are in 167 grams?

11. Example: How many centimeters in 72 inches?
How many yards are in 810 inches?
If I run 5 miles per hour, how many meters per second do I run?
