The unit that is used in the denominator is the one to cancels the unit that appears in a numerator.

∙ 10y agoThe unit itself isn't important, because dimensional analysis works on the principle that multiplying a number by 1 leaves it unchanged. In this case, the conversion factor simply acts as the "1", or equivalent or what you're trying to convert but with different units. As a general way of thinking about this, the denominator unit should just be able to cancel itself out so that you get a new unit which would be the numerator. To do this, the conversion factor should be multiplied by the unit in its denominator. For example, if you know that a substance is 1 gram per cubic centimeter, you'll multiply it by a conversion factor which has grams in the denominator. When the units in a denominator multiply by the units of a numerator, they cancel out so your new answer is in cubic centimeters. You can also flip the conversion factors around to make it work, based on the values of the units that you know.

∙ 9y agoAssuming 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.

What must be true for a ratio of two measurements to be a conversion factor?
The measurements must be equal to each other.
What is convertion factor?
One thing that a conversion factor does is changes the numerical amount (value) of the measurement. The second thing a conversion factor does is changes the way measurement is expressed (units).
Is conversion of steam to water an exothermic reaction?
No. Converting water to steam is endothermic because the water must absorb heat from its environment.
How do you calculate enrichment factor of Zn in soil?
To calculate the enrichment factor of the Zn in soil, one must use the Proton Eclat emulator. On the emulator, select the soil type and then determine the nucleus of the enrichment on the soil.
Can you use bleach and vinegar to help control Iron in well water?
No. -Iron must be filtered out by different methods. Get a sample tested to know how much iron you have.No. -Iron must be filtered out by different methods. Get a sample tested to know how much iron you have.
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 units of a conversion factor must be in the denominator?
The denominator must contain the unit that you wish to cancel in the numerator of the other number.
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.
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.
How do you which unit of conversion factor must be the denominator?
It must be the unit of the measurement that you are converting FROM.
How do i know which unit of conversion factor must be in the numerator?
The numerator must contain the unit INTO which you are converting.

What is the rule for the denominator of recuring decimals?
They must have at least one factor other than 2 and 5.
Which unit of a conversation factor must be in the denominator?
It is the unit of the measurement which you are converting FROM.
Must a conversion fraction equal one?
No. It would be very unusual for a conversion factor to equal one.
How can you add two fractions with denominators of 10 and end up with a sum whose denominator is 5?
A fraction with denominator 10 must have an odd numerator for otherwise its numerator and denominator would have 2 as a common factor and it would be simplified so that it would no longer have 10 as a denominator. So you are adding two odd numerators, both with 10 as the denominator. The sum of two odds is always even, so the result will be an even sum with 10 as the denominator. So in the answer, 2 is a common factor of the numerator and denominator and the answer can be simplified. If there is no other common factor, then the answer must have a denominator of 5.
