Question

1 degree on celsius scale is equal to

• A. $\frac{9}{5}$ degree on fahrenheit scale
• B. $\frac{5}{9}$ degree on fahrenheit scale
• C. 1 degree on fahrenheit scale
• D. 5 degree on fahrenheit scale

Answer 1

The correct option is A

$\frac{9}{5}$ degree on fahrenheit scale

Ice point: 0 degree celsius = 32 degree fahrenheit

Steam point: 100 degree celsius = 212 degree on fahrenheit.

Therefore, 100 degree rise on celsius scale is equal to 180 degree rise on fahrenheit scale.

Hence, 1 degree on celsius scale is equal to $\frac{180}{100}=\frac{9}{5}$ degree on fahrenheit scale.
