The same way you convert a positive temperature from Fahrenheit to Celsius. It's exactly the same formula. You probably should have asked something like "How do you do arithmetic with negative numbers?".
Exactly the same way you convert a positive Fahrenheit to Celsius. The conversion
process doesn't care whether either one is positive or negative.
-- Take the Fahrenheit.
-- Subtract 32 from it.
-- Multiply the result by 5/9.
-- You've got your Celsius.
Use the formula: oF = 1.8*(oC) + 32o So for example -15oC would be: oF = 1.8(-15o) + 32 oF = -27 + 32 oF = 5o
F to C: Deduct 32, then multiply by 5, then divide by 9
C to F: Multiply by 9, then divide by 5, then add 32
(-10) degrees Celsius = 14 degrees Fahrenheit.
-50 degrees Fahrenheit = -45.5 degrees Celsius.
-30 degrees Fahrenheit = -34.4 degrees Celsius.
(minus 17) degrees Celsius = 1.4 degrees Fahrenheit
-15ºC = 5.0ºFUse this formula to convert degrees Celsius (C) to degrees Fahrenheit (F): (C x 1.8) + 32 = F
(-10) degrees Celsius = 14 degrees Fahrenheit.
To convert from celsius to fahrenheit use the following formula : F = (C * 9/5) + 32
-50 degrees Fahrenheit = -45.5 degrees Celsius.
-30 degrees Fahrenheit = -34.4 degrees Celsius.
(minus 17) degrees Celsius = 1.4 degrees Fahrenheit
Start by taking the number in Celsius and multiply it by 9. Then divide that number by 5, and then add 32. This is how you convert Celsius to Fahrenheit or use the equation F = (9/5)C + 32In this case, the answer is about -22 degrees Fahrenheit.
To convert Celsius to Fahrenheit - Multiply the Celsius value by 1.8 THEN add 32 To convert Fahrenheit to Celsius - Subtract 32 from the Fahrenheit value THEN Divide by 1.8
-15ºC = 5.0ºFUse this formula to convert degrees Celsius (C) to degrees Fahrenheit (F): (C x 1.8) + 32 = F
-15ºC = 5.0ºFUse this formula to convert degrees Celsius (C) to degrees Fahrenheit (F): (C x 1.8) + 32 = F
147 Fahrenheit convert to Celsius
Use this equation to convert degrees Fahrenheit (ºF) to degrees Celsius/Centigrade (ºC): [°C] = ([°F] - 32) × 0.556Use this equation to convert degrees Celsius/Centigrade (ºC) to degrees Fahrenheit (ºF): [°F] = [°C] × 1.8 + 32
-7.6 Fahrenheit
