Question

How do you convert tempertures from celsius to fahrenheit?

Answer 1

An easy, not not precise method;

F to C) subtract 32 & halve the remainder.  Example 90F; 90-32=58.  58/2=29C

C to F) double C & add 32.  Example 20C; 20*2=40 +32 = 72C.

The exact ratio is 9/5, plus or minus 32.

Remember 0C is 32F (freezing point).

Like I said, it's not exact, especially at higher temps, but for traveling or quick converting it works just fine.

Answer 2

(cx1.8) = 32

Answer 3

In the formulas below, / means to divide, * means to multiply, - means subtract, + means to add and = is equal. Tc = temperature in degrees Celsius, Tf = temperature in degrees Fahrenheit

To convert a Fahrenheit temperature into Celsius:

Tc = (5/9)*(Tf-32)

For example, to convert a Fahrenheit temperature of 98.6°F into degrees Celsius, first subtract 32 from the Fahrenheit temperature to get 66.6. Then you multiply 66.6 by five-ninths to get 37°C.

To convert a Celsius temperature into degrees Fahrenheit:

Tf = ((9/5)*Tc)+32

For example, to convert a Celsius temperature of 100 into degrees Fahrenheit, first multiply the Celsius temperature reading by nine-fifths to get 180. Then add 32 to 180 and get 212°F.

The Celsius temperature scale is still sometimes referred to as the "centigrade" scale. Centigrade means "consisting of or divided into 100 degrees." The Swedish Astronomer Andres Celsius (1701-1744) developed the centigrade scales for scientific purposes. It has 100 degrees between the freezing point (0°C) and boiling point (100°C) of pure water at sea-level air pressure. An international conference on weights and measures voted to name the centigrade scale after its inventor in 1948.
