How do you know which unit of a conversion factor must be the denominator?
It is the units for the measurement which you are converting FROM.
How do you know which unit of conversion factor must be the denominator?
The unit that is used in the denominator is the one to cancels the unit that appears in a numerator.
What conversion factor would you use to convert between these pairs of units?
To answer that accurately, we will need to know the pairs of units.
How do you convert 90 miles per hour into feet per second?
You need to know the conversion rates for both miles to feet AND hours to seconds. There are 5280 feet in a mile and 3600 seconds in an hour. 90mi/1hr (5280 ft/mi)(hr/3600 s) You want the units to cancel out, so that's how you decide to put mi and hr in the numerator or the denominator. For miles to cancel out, it has to be in the denominator of the conversion factor and vice versa for hours. After the units cancel out, you're left with: (90)(5280 ft)/(3600 s) = 475200 ft/3600 s = 132 ft/s
How can I convert measurement of weight?
To convert a weight measurement, you need to know the conversion factor. For example, to convert pounds to kilograms, you multiply the number of pounds by 0.45. To convert kilograms to pounds, divide the number of kilograms by 0.45. Use the appropriate conversion factor depending on the units you are converting between.

How do you know which unit of conversion factor must be in the denominator when you're doing a conversion problem?
These are the units which are used for the measurement that you are converting FROM.

To answer that accurately, we will need to know the pairs of units.
How do you know which unit of conversion factor must be a conversion factor?
Assuming you are talking about stoichiometery a conversion factor is often a number with two units. For example a conversion factor could be Miles per hour (Miles/hour). If you had miles and needed to convert to hours you would multiply the miles by Hours/miles so that the miles would be canceled out (miles/miles = 1). Then your units left would be hours. Or vice versa. There are other factors like this in chemistry like grams/mol Mol/liter etc. To put it shortly the conversion factor denominator is always paired with the numerator.
How do you convert synthase units to International units?
I know that Synthase Units are used to qualify enzymatic ability to synthesis molecules its indicated for. I don't know that a conversion factor is available to this. However, some supplements use International units IU and others use synthase units SU so how do you make a comparison if you don't have a conversion factor?
How will you change unit of measure for area?
You need to know the conversion factor for the two units you are using.
When working with conversion problem why should units be included?
You need to know which units you are converting from and to.
How do you convert 90 miles per hour into feet per second?
You need to know the conversion rates for both miles to feet AND hours to seconds. There are 5280 feet in a mile and 3600 seconds in an hour. 90mi/1hr (5280 ft/mi)(hr/3600 s) You want the units to cancel out, so that's how you decide to put mi and hr in the numerator or the denominator. For miles to cancel out, it has to be in the denominator of the conversion factor and vice versa for hours. After the units cancel out, you're left with: (90)(5280 ft)/(3600 s) = 475200 ft/3600 s = 132 ft/s
How do you know whether you have chained fractions correctly when you are changing a measurement to different units?
Select a conversion factor so that canceling removes the undesired unit and leaves the desired unit.
How much is 9.5 in feet?
To make the conversion, we'd have to know both units.
