They are equal at -40° (minus 40 degrees).

...because if we convert the readings of Celsius and Fahrenheit, we will have:

Celsius to Fahrenheit (-40°C x 9/5) +32 = -72 + 32 = -40°F

Fahrenheit to Celsius (-40°F - 32°) x 5/9 = (-72 )x 5/9 = -40°C

Algebraically (for the numerical value T)

The formula for some identical temperature T would be

T(°F) = T(°C) and T = (9/5 T + 32) yields 4/5 T = -32 and T = -40

What the two scales for temperatures?

Fahrenheit and Celsius


To convert Celsius temperatures to Fahrenheit temperatures quickly without?

You can quickly estimate Fahrenheit temperatures from Celsius by doubling the Celsius temperature and adding 30. This will give you an approximate Fahrenheit equivalent. For example, if it's 20°C, double it to get 40, then add 30 to get 70°F.


Why is it that temperatures at -40 degrees celsius and Fahrenheit are the same?

There are two reasons for this. The first is that a Fahrenheit degree is smaller than a Celsius degree. Four Celsius degrees is the same size as nine Fahrenheit degrees. The second reason is that 32 degrees Fahrenheit is zero degrees Celsius. If you put those two ideas together you figure out that -40°F = -40°C.


Temperatures at which both Fahrenheit and Celsius are equal?

The temperature at which both Fahrenheit and Celsius are equal is -40 degrees.


WHICH IS FALSE 5 degrees celsius is warmer than 5 degrees Fahrenheit 15 degrees CELSIUS IS COOLER THAN 60 DEGREES FAHRENHEIT 30 DEGREES CELSIUS IS WARMER THAN 90 DEGREES FAHRENHEIT 35 DEGREES CELSIUS?

I suggest you convert each of the Fahrenheit temperatures to Celsius (or the other way round, each of the Celsius temperatures to Fahrenheit), and then compare.

What temperatures are impossible to measure -85 degrees Fahrenheit -50 degrees celsius -20 degrees celsius or 545 degrees Fahrenheit?

Temperatures cannot be negative, so it is impossible to measure -85 degrees Fahrenheit or -50 degrees Celsius. All the other temperatures given, -20 degrees Celsius and 545 degrees Fahrenheit, are possible to measure.


What is the Fahrenheit to Celsius ratio?

1 Fahrenheit degree = 5/9 of one Celsius degrees 1 Celsius degree = 1.8 Fahrenheit degree There is no constant ratio between the °F and °C numbers for the same temperature, because their zeros are at different temperatures. A Celsius number less than -40° is colder than the same Fahrenheit number. A Celsius number more than -40° is warmer than the same Fahrenheit number. And -40° is the same actual temperature in both °F and °C.


What is 15000000 degrees celsius in Fahrenheit -?

Temperatures in that range are associated with stellar fusion, and are usually expressed in Kelvin, which is practically the same as Celsius for those high temperatures. However, 15 million °C would equal 27 million °F. Fahrenheit is almost never used for such high temperatures. Celsius and Kelvin are normally used. But 15 million degrees on the Celsius scale would be approximately 27 million degrees on the Fahrenheit scale.
