Question

Reena is suffering from high fever since night. Her aunt measures her body temperature to

390C using a celcius thermometer. But she wants to know this temperature in Fahrenheit scale

before leaving for doctor's clinic. Help her to convert this temperature on fahrenheit scale.​

Answer 1

ANSWER

Celsius to kelvin is: °C +273

Therefore if the temp. was 390C it should be 390 + 273 = 663.

Answer 2

ANSWER:

The formula used for converting Celsius to Fahrenheit is $0^{\circ} \mathrm{C} \times\left(\frac{9}{5}\right)+32=32^{\circ} \mathrm{F}$

EXPLANATION:

GIVEN:

The reading shown in the thermometer is $390 ^{\circ}\text{C}$

SOLUTION:

Now Reena can convert the reading using the temperature calculator or she can convert 'Celsius to Fahrenheit' with following formula.

Now, Multiplying the degree reading by (9/5) and adding to 32 to give the Fahrenheit reading.

Hence by substituting the value of Celsius in the formula,  we get

$390 \times\left(\frac{9}{5}\right)+32=734^{\circ} \mathrm{F}$
