Unit Conversion

In this video you will learn how to set up unit conversions.

In this video I convert 5 feet to meters, and 1 mile to kilometer.

In problem 1 I converted 5 feet to meters.

Here is what the conversion looked like. I knew that 1 inch equals 2.54 centimeters, and 12 inches equals a foot.

5 feet/1 x 12 inches/1 foot x 2.54 cm/ 1 inch x 1 meter/100 cm

Next you cancel and multiply straight across.
You end up with 5 feet = 1.524 meters
Another key to solving the problem is to always place a 1 by the largest unit of the fraction.

In order to solve 1 mile = _____ kilometers, I knew 5280 feet = 1 mile, and 12 inches are in a foot.
Here is how I set it up.

1 Mile/1 x 5280 feet/1 mile x 12 inches/1 foot x 2.54 cm/1 inch x 1 meter/ 100 cm

One helpful hint. After you have set up your conversion, the unit you are converting to should be on the top.

Hope this video a quick explanation helps with your unit conversion.
