Question

If you did not learn a different method for unit conversion in a previous class, respond to the following statement.

Explain how to use the unit-factor method to convert 120 pounds to kilograms.
Hint: 1 kilogram=2.2 pounds
To write the unit factors, use the / symbol, like this: 1 gallon/3.79 liters.

Answer 1

120 pounds = 54.5 kilogram

Explanation:

We know that,

1 kilogram=2.2 pounds

or

1 pound = (1/2.2) kilogram

We need to convert 120 pounds to kilograms.

`120\ \text{pounds}=(120)/(2.2)\ \text{kilogram}\\\\=54.5 \text{kilogram}`

So, there are 54.5 kilograms in 120 pounds.
