What is this temperature in degrees Fahrenheit?

The official record for the lowest temperature ever recorded on Earth was set at Vostok, Antarctica, on July 21, 1983. The temperature on that day fell to −89.2∘C, well below the temperature of dry ice. Express your answer using four significant figures.

The freezing point of water is 0˚C and 32˚F. On a Celsius thermometer there are 100˚ betqwwn freezing and boiling points, In ˚F, the boiling point of water is 212˚. 212 – 32 = 180˚ The ratio of Fahrenheit degrees to Celsius degrees is 180 : 100. This is 1.8. The following equation is used to convert Fahrenheit degrees to Celsius degree, F = 1.8 * C + 32 F = 1.8 * -89.2 + 32 = -128.56˚ To four significant figures, this is -128.6˚. I hope my explanation is helpful for you.

2Fitt gave you the formula but you cannot express it to four significant figure without another decimal place on the C-scale. Remember what GIGO stands for.

(℃ * 9/5) + 32 = ℉
