The third significant figure of a number is the digit after the second significant figure. This is true even if the digit is zero, and so on. … We round a number to three significant figures in the same way that we would round to three decimal places. We count from the first non-zero digit for three digits.
How many significant figures does 0.0040 have?
The number 0.0040 has two significant figures. The first three zeros mark the decimal place and are not significant. The last zero indicates accurate measurement to the third decimal place with some uncertainty at the fourth decimal place, so the 4 and last 0 are considered significant.
