How we got this formula i know that the ratio of scale difference is 180/100 =9/5 but why to add 32, is it because °F at 0°c is + 32
The 0 was moved to be the freezing point of water. Here is some info:parshyaa said:How we got this formula i know that the ratio of scale difference is 180/100 =9/5 but why to add 32, is it because °F at 0°c is + 32

(interestingly, originally the freezing point of water was 100°C, and the boiling point was 0°C, but Carl Linnaeus made that modification- Good read)
Ha that is a cool way to see it.James Pelezo said:
FactChecker said:I'm not sure how clear it is in the references, but for seafaring nations like Britain and Denmark, the freezing temperature of salt water is very significant. So setting the 0 of the Fahrenheit scale at that point makes sense. Maritime issues drove the development of clocks, thermometers, etc.
I am certainly not an expert in the history of this. I have seen it said a few times that 0°F is the freezing point of brine. (This reference says that 0°F was the lowest temperature he could get reliably by freezing brine. https://en.wikipedia.org/wiki/Brine . That makes sense to me.) I might have seen it explained as important for sailing, I don't remember. Maybe I just erroneously jumped to that conclusion. Certainly he would have wanted to include the temperature of freezing sea water in his temperature range.David J Wilson said:I fortified myself to argue with you with the aid of Google, which asserts that seawater freezes at 28.4°F. I seem to remember that Fahrenheit produced the lowest temperature possible to him in the day in his laboratory to get to his zero.

The formula for converting Celsius to Fahrenheit is °F = 9/5(°C) + 32. This equation represents the relationship between the two temperature scales.
The number 32 is used in the formula because it represents the freezing point of water in Fahrenheit. When water freezes, it becomes solid at 32°F.
To convert a temperature from Fahrenheit to Celsius, you can use the formula °C = (°F - 32) * 5/9. This equation is the inverse of the formula for converting Celsius to Fahrenheit.
The formula for converting Celsius to Fahrenheit is an approximation and may not always give an exact conversion. This is because the two temperature scales use different intervals for measuring temperature. However, for most practical purposes, the formula is accurate enough.
Yes, you can use the formula for converting Celsius to Fahrenheit for any temperature. It is a mathematical equation that can be applied to any value in Celsius to get the corresponding value in Fahrenheit.
