Answer:
The metric system uses the Celsius scale to measure temperature.
Explanation:
Water freezes at 0o Celsius and boils at 100o Celsius which is a difference of 100o. Water freezes at 32o Fahrenheit and boils at 212o Fahrenheit which is a difference of 180o. Therefore each degree on the Celsius scale is equal to 180/100 or 9/5 degrees on the Fahrenheit scale.
How to convert Celsius temperatures to Fahrenheit
Multiply the Celsius temperature by 9/5.
Add 32o to adjust for the offset in the Fahrenheit scale.
Example: convert 37o C to Fahrenheit.
37 * 9/5 = 333/5 = 66.6
66.6 + 32 = 98.6o F
