It is possible to estimate the temperatures in Celsius.

Celsius is used as a unit of measurement in most countries.If you don't have access to the Internet, you can use the following methods to get a good estimate.

Step 1: Determine the temperature

There is a temperature display.The temperature is displayed on many public clocks.If you can't locate a temperature display, ask someone to tell you the temperature.

Step 2: Divide the temperature by 2.

You can use a calculator or use the numbers in your head.You want to double this number.

Step 3: 30 is added to the number.

Add 30 to the doubled number.You can perform the addition in your head or use a calculator.It will give you an approximate temperature.If you add 30 to the number 40, you have a temperature of 70 degrees.

Step 4: The temperature must be determined.

There is a temperature display.There is a public clock on a building.The temperature is displayed below the time on many public clocks.If you can't locate a temperature display, ask someone to tell you the temperature.

Step 5: Take the temperature and add it to 2.

You can use a calculator or use the numbers in your head.You want to double this number.

Step 6: Take 10% out of the number.

If you divide the number by 0.1, you can calculate 10%.100 x 0.1 is an example.10 is the number.You doubled the number in the first calculation.For the best results, use a calculator.

Step 7: 32 is added to the number.

Add 32 to the doubled number.You can perform the addition in your head or use a calculator.This will tell you the temperature in Fahrenheit.Determine the temperature in Celsius: 20 degrees Multiply this number by two and then subtract the number from your number in step two.

Step 8: Refer to rough comparable temperatures by heart.

These numbers are easy to memorize and will allow you to convert quickly.Use multiples of 0 degrees Celsius and 32 degrees Fahrenheit to remember.50 degrees is equal to 10 degrees.70 degrees is equal to 20 degrees Celsius.86 degrees Fahrenheit is equivalent to 30 degrees Celsius.104 degrees is equal to 40 degrees.

Step 9: Understand comparable temperatures by heart.

These numbers are easy to memorize and will allow you to make precise conversions.Use multiples of 5: -5 degrees Celsius equals 23 degrees Fahrenheit.41 degrees is equal to 5 degrees Celsius.59 degrees is equal to 15 degrees Celsius.77 degrees is equal to 25 degrees Celsius.95 degrees is equivalent to 35 degrees.

Step 10: You can learn similar temperatures by heart.

Use multiples of 10 to convert 32 degrees Fahrenheit to 0 degrees Celsius.It is equivalent to 4.2 degrees Celsius.10 degrees is equal to 50 degrees.60 degrees is equal to 15 degrees Celsius.70 degrees is 21.2 degrees Celsius.The temperature is equal to 26.6 degrees Celsius.
