Question

A measured temperature on Fahrenheit scale is 200 °F. What will this reading be on Celsius scale?
(i) 40 °C
(ii) 94 °C
(iii) 93.3 °C
(iv) 30 °C

Answer 1

Ans ;93.3 ,as
F= 9/5( degree C) + 32

200 = 9/5 (c ) +32

(200 -32) x5 / 9 = C

C = 93.3

Answer 2

Answer : The correct option is, (iii) $93.3^oC$

Solution :

As we are given the temperature reading in Fahrenheit scale. Now we have to calculate the temperature reading in Celsius.

Conversion factor used to convert Fahrenheit to Celsius.

$^oC=\frac{5}{9}\times (^oF-32)$

Now put the value of Fahrenheit in this formula, we get the reading in Celsius.

$^oC=\frac{5}{9}\times (200^oF-32)=93.3^oC$

Therefore, the temperature reading in Celsius is, $93.3^oC$
