multiply
By subtraction. For example 2 - 1 = 1
You convert to a larger unit. Smaller to larger. Metre is 1000 times larger than a millimetre
The decimal would go left. For example: 18.0: Smaller: 1.8 Bigger: 180
If you convert to a common unit - either multiply kilograms by 1000 to convert to grams, or divide grams by 1000 to convert to kilograms - you can compare them, and see which one is bigger.
you divide the smaller # into the bigger #----
multiply
The number is bigger.
bigger!!

To convert from a larger unit to a smaller unit you would multiply. Ex: 5 km = 5000 m Where 1 km = 1000 m <><><><><> It depends on which factor you are multiplying or dividing by. It can go either way. To convert from ounces to grams, for instance, you can divide by 28.350, or you can multiply by 0.035273.
To move to a larger measure, divide by s-cubed where s is the scale factor between the smaller linear measure and the bigger one. For example, To convert from cm3 to metre3 , 1 cm = 0.01 m so n cm2 = n*(0.01)3 cubic metres.
You expect to end up with fewer of the large unit than you had of the small unit. Multiplication usually gives a bigger number than you started with. Division usually gives a smaller number than you started with.
The decimal would go left. For example: 18.0: Smaller: 1.8 Bigger: 180
You have a bigger number. Each single kilometer turns into 1,000 meters.
Bigger. To convert from meters to centimeters, you need to multiply by 100. To convert from centimeters to meters, you need to divide by 100.
