Why you need to multiply when converting from a larger unit to a smaller unit?

Because if you measure the same amount but with a smaller unit, you expect to
wind up with a bigger number of them. For example, there are more teaspoons of
water in a swimming pool than gallons of water in the same pool.
If you expect to have a bigger number after converting the units, then multiplication
is definitely the way to go.

Is 72 inches smaller than 3 yards?
You need to convert everything to the same units, then compare. Converting yards to inches is easiest; since a yard has 3 feet, and a foot has 12 inches, that means that a yard has 36 inches - so to convert from yards to inches, you multiply by 36.
Why do you use multiplication to change a larger unit to a smaller unit?
When you change from a larger unit to a smaller unit there will be more of them; thus you multiply. eg millimetres are smaller than centimetres. Thus it requires many more of them to measure the same distance. Thus when converting metres to millimetres a multiplication will be required. If you draw a line 3.5 cm long with your rule, and then measure it in mm you will find that it takes 35 mm. If you look closely you will see than 1 cm = 10mm, thus 3.5 cm = 3.5 × 10 mm = 35 mm.
How do you write the conversion factor you would multiply by inches to feet?
The large value converting to small value is multiplied. The small value converting to large value is divided. inches (small value) to feet (large value) is divided. The number of inches in a feet is 12 inches, so to convert inches to feet, one would need to divide the number by 12.
Why do smaller populations need larger sample sizes?
They do not. Population size does not affect the sample size. The variability of the characteristic that you are trying to measure and the required accuracy will determine the appropriate sample size.
Do you multiply or add with volume?
To find out volume you need to times length by breadth by height
How do you do math for converting 1200psi to pascals?

When you multiply a decimal by a whole number why is it smaller?
It need not be. 1.5 * 6 = 9, which is bigger than 6, not smaller.
Why do you use division to change a smaller unit to a larger unit in conversions?
There are lots of small units in each big unit. As a result, the number of small units is greater and to go from a greater number to a smaller number you need to divide by a number which is biiger than 1.Alternatively, to change a smaller unit to a larger unit you can always multiply by a number which is between 0 and 1.

Why semi cone angle is set between10 degree and 15 degree?
It does not need to be. It can be smaller or larger.
How do you use prime factors to help you multiply by 18?
Presumably, the theory is that it's easier to multiply by small numbers than larger ones. If there's a number that you need multiplied by 18, multiply it by 3, then multiply that total by 3, then multiply that total by 2.
