# What is 19°F in celsius?

##### 1 Answer

#### Explanation:

In order to determine how many degrees 19 Fahrenheit is in Celsius we need to understand that there is an equation that we must use. To convert a temperature in Fahrenheit to Celsius that equation looks like this:

Now we can solve for **order of operations** (PEMDAS).

**-------------------------------**

Here's a quick refresher on PEMDAS:

**First (P):** we do anything in **parentheses**

**Second (E):** we do anything raised to a power, **exponents**

**Third (M):** we do any **multiplication**

**Fourth (D):** we do any **division**

**Fifth (A):** we do any **addition**

**Sixth (S):** we do any **subtraction**

**-------------------------------**

Okay now that's out of the way let's solve!

Okay this might look intimidating but, its not I promise.

Is the same as this:

You could cheat by plugging this into a calculator but lets take a look at

Now,

In fact this holds true for any number less than 9 that is over 9 (all numbers up to

For all intents and purposes we can round this to 0.556. Now we can multiply -13 by 0.556, this will give us the number of degrees Celsius:

We can round to get:

**-------------------------------**

In order to go from Celsius to Fahrenheit we can use this equation:

Instead of plugging in Fahrenheit we would plug in Celsius. For example: "What is -7.2^oC in Fahrenheit?"

I hope this helps!
