How many significant figures are in temperatures?

Answer 1

Significant figures are basically the amount of digits in a number.

E.g.

2.576 has 4 significant figures

32.545 has 5 significant figures

Zeroes before the first non-zero digit and after the last non-zero digit are not counted as significant figures.

E.g.

0067.4 has 3 significant figures

67.400 has 3 significant figures

0067.400 has 3 significant figures.

In case of thermometer measurement of normal temperatures maximum three digits are significant because most of the thermometers indicate one digit after decimal; as 37.4.

Answer 2

Temperatures are typically measured with 1-2 significant figures, as precision beyond that is usually not needed for everyday purposes. However, in scientific contexts, temperatures can be measured with more significant figures depending on the sensitivity of the measuring instrument.

Answer 3

10,000 .
