••• Marie Mulrooney

Despite the Metric Conversion Act of 1975, the United States remains one of very few countries that still uses the Fahrenheit temperature scale. However, scientists everywhere, including in the U.S., work with the Celsius temperature scale. So being able to convert between Celsius and Fahrenheit will come in handy if you're doing science, traveling to another country or conversing with anybody from almost any other country in the world.

    Substitute 10 into the formula for degrees Celsius.

    Plug the Celsius temperature you are converting from into the formula. For this example, try converting 10 degrees Celsius into Fahrenheit.

    Ten times 9 equals 90.

    Multiply the degrees Celsius by 9.

    Ninety divided by 5 equals 18.
