How many significant figures are in temperatures? - Answers
Web27 jan. 2024 · The first thing to note here is that the original measurement has 4 significant figures, the number of sig figs you have in its mantissa. 7.379 ⋅ 10−4 → 4 sig figs: {7,3,7,9} Now, you're using a conversion factor to take you from cubic meters to cubic centimeters. 1 m3 = 1003 cm3. Because 1 m3 is defined as being equivalent to 100 cm3 ...

Web28 jul. 2024 · Use the significant figures associated with the temperature in Kelvin. Recall that when adding/subtracting numbers, you don’t round sig figs, but rather, just round to the least accurate decimal place. So 25°C becomes 298 K with three significant figures, since 25 + 273.15 should be rounded to no decimal places. Use the significant figures associated with the temperature in Kelvin.
