- Check to see if your answer makes sense.
What is the factor label method?
The factor-label method is a technique for converting units of measurement into other units of measurement. The technique uses conversion factors that are made from equalities between units. The conversion units are arranged in fraction form in such a way as to cancel all other units except the desired unit.

What is a factor label problem?
Dimensional Analysis (also called Factor-Label Method or the Unit Factor Method) is a problem-solving method that uses the fact that any number or expression can be multiplied by one without changing its value.
How do you do the conversion factor method?
To find the conversion factor needed to adjust a recipe that produces 25 portions to produce 60 portions, these are steps you would take:Recipe yield = 25 portions.Required yield = 60 portions.Conversion factor. = (required yield) ÷ (recipe yield) = 60 portions ÷ 25 portions. = 2.4.

What are the methods used to measure dimensional analysis?
Dimensional analysis (also called factor label method or unit analysis) is used to convert from one set of units to another. This method is used for both simple (feet to inches) and complex (g/cm3 to kg/gallon) conversions and uses relationships or conversion factors between different sets of units.

What Is the Factor-Label Method
The factor-label method, also called dimensional analysis or unit conversions, is used to convert from one unit of measurement to another unit. This method works because numbers can be multiplied by one without changing their value. It is called the factor-label method because it uses factors that are equivalent.
Conversions with the Factor-Label Method
The factor-label method can be used to convert between units in the metric system. It can also be used to convert between the metric system and other systems of units.
Ever lost points on a test because you forgot to write the units?
Rightfully so! Numbers have no meaning without their units of measurement. Two can be greater than 12. Three can equal one. This is all dependent on the unit of measurement being used. In your general chemistry class, you will encounter measurements of all sorts. These measurements include time, length, mass, volume, and many more.
Conversion factors and their use
A conversion factor is used to change the unit of measurement without changing its value. On your general chemistry exam formula sheet, you will see them as equalities where opposite sides of the equal sign are a given measurement expressed in different units:
The science behind the factor-label method
First things first, the conversion factor, initially given to you as an equality, needs to be written as a fraction. What side of the equal sign goes in the numerator and what side goes in the denominator? It depends! But we’ll get to that soon.
