WebAnswer (1 of 7): Think about it this way: The measured value of 23 °C is (apparently) significant to the 1’s place. The conversion factor from Celsius to Kelvin is significant to beyond the 1’s place: it is defined as exactly 273.15. Your conversion has rounded this off to 273, which leaves it ... WebJun 9, 2024 · Significant figures are used to ensure that a measurement is honest and accurate.
