Algorithm and Flowchart to convert temperature in Celsius to Fahrenheit
The input for this algorithm is temperature in degree Celsius.
The output is temperature in degree Fahrenheit.
Formulae:
F = 9/5 * C + 32
The algorithm to convert temperature in degree Fahrenheit is as follows:
Algorithm:
Name of Algorithm: Convert temperature in degree Celsius to Fahrenheit.
Step 1: Start
Step 2: Read temperature in Celsius as ‘C’
Step 3: F = 9 / 5 * C + 32 [Convert to Fahrenheit]
Step 4: Display F
Step 5: Stop
Flowchart:
Tracing:
Let C = -40
F = 9/5*-40 + 32
F = -40
It displays -40 degree fah. as output.
