Measurement Units Section 1: Converting

Mixed Measurement Many times you will see English units written in

combination with other English units. Let’s see what it takes to convert mixed

units like these. One of the reasons for converting mixed units is that the

arithmetic is easier. And here’s an example where we have a diagram given in

mixed units, feet and inches, and the question is what’s the overall length. Much

easier to convert these mixed units all into one unit of measure and whether you

convert them into equivalent inches and then add them all together or whether

you convert those mixed units all into feet equivalent measurements of feet and

add them up is going to make the task of finding overall length much easier. Here’s an example of converting mixed

units. We have four pounds five ounces and we want to find an equivalent all

pound measurement. While the four-pound portion is already in pounds

so no attention is needed for that however we need to convert the five

ounces into an equivalent pound measurement. We will take that value

express it as a fraction with the denominator of one. We’re going to

multiply it by one our conversion factor fraction where the arrangement of

those values equivalent values will be such that ounces are canceling out one

another and leaving us with a unit of pounds. When we’d look up the

relationship we find that 16 ounces is equivalent to one pound. The 16 ounces

goes in the denominator with the equivalent one-pound in the numerator.

There we have our fraction value equivalent to one. Multiplying then we

cancel out common values in the numerator and the denominator

multiplying numerator values next we get a five. Multiplying denominator values

we get a sixteen 5/16 to replace the fraction with a decimal equivalency

we end up with .3125 pounds. We now can take that equivalent to the

five ounces combine it with the four pounds to give us a final single unit

measurement that’s equivalent to the given of 4.3125 pounds. For additional

practice look in your text book on page eight.
