If you run a mile in 6 minutes per mile,what is this time converted to kilometers per mile? This would be an example of a unit conversion. You may need to convert time,distance, volume, moles in chemistry, and many more type conversions.
This method that I will show you helps to take the confusion out of unit conversions by using colors and boxes in order to help organize the conversion.
Follow these easy steps, and then watch the video in order apply this method to unit conversions.
Step 1. Write down your starting units and your goal units.
Step 2. Look at the numerator of the starting units, and the numerator of the goal units. Ask yourself " Do they match?
Step. 3. If the units are not the same, circle the units with the same color, and draw a box in the same color.
Step. 4 Use one color to highlight the units of measurement in the DENOMINATORS. Ask yourself, do they match? If the units of measurement do NOT match, draw a square.
Step. 5 Fill in the yellow square. For this example, MILES (mi) and FEET (ft) will go in the yellow square, and hours and minutes will go in the green box.
Place MILES (mi) in the numerator so you can cancel miles, and FEET (ft) has to go in the DENOMINATOR inside the yellow square.
Step. 6 Repeat for the hour and minutes in the green box.
Step. 7 Cancel units and multiply straight across.
The final answer will be 616 feet/minute
