Fahrenheit Celsius Thermometer
A Fahrenheit Celsius thermometer is a device used to measure temperature. Many models will display the results in Fahrenheit and Celsius. However, the Celsius is the most widely used temperature’scale in the world.
How to Read the Temperature in a Thermometer
For a Celsius thermometer, remember that zero is the freezing point and 100 the boiling point. The interval is segregated into 100 degrees or parts.
In the Fahrenheit system, the boiling point is 212 degrees and the freezing point is 32. The intervals are 180 degrees. Each Fahrenheit degree is equivalent to 5/9 or 1.8 of a Celsius degree.
Converting between the Temperature Scales
To convert Celsius into Fahrenheit, multiply the degrees by 1.8 and add 32 to the total. Assume you want to change 10 C to F. You just multiply the 10 by 1.8 and add 32. The total is 50. This is the equivalent of the degrees in Fahrenheit.
When using Fahrenheit Celsius thermometers, being able to convert to Celsius will also be necessary. Begin by subtracting 32 from the total. Multiply this by 0.556 or 5/9.
Here is an example: if the thermometer states 68 F remove 32 so you will end up with 36. Multiply the 36 by 5/9. The total is 29; this is the equivalent in Celsius.
Negative and Positive Signs
There are times when the negative C will turn into a positive when changed to the F scale. Suppose the thermometer shows a reading of -5 C. When you convert it to Fahrenheit, (multiply 5 x 1.8 + 32) the result is -9 F. This results in 23 F. Do not add 32 with 9 because the total would be 41 F, which is wrong.
Who Invented the Fahrenheit?
The scale was created by Daniel Gabriel Fahrenheit (1686-1736) in 1724. He was a scientist who specialized in the analysis of temperatures. With the freezing point at 32 F and the boiling point at 212 F, the freezing and boiling point are 180 degrees distant.
A closer inspection will show that the interval between the boiling and freezing point is 1/180. By comparison, the freezing and boiling distance in Celsius is 100 degrees.
Today’s Fahrenheit Celsius thermometer no longer requires the user to do various conversions. The results will be displayed automatically. However, knowing how to do the conversion is necessary for those whose thermometers only show readings in C or F.
