# The number of significant figures is the measurement 170.040 km is?

170.040 has six significant figures. A significant figure is any non-zero digit or any embedded or trailing zero. Leading zeros are not significant.

### What determines the number of significant figures that should be retained in recording measurements?

### How many significant figures are in the measurement 33050 grams?

There are four significant figures in 33050. The trailing zero is not significant because there is no decimal. There would be five significant figures in 33050. If we were to remove the last zero in the number, we would alter the value of the number. Had the number been 3305.0, then there would have been four significant digits.

### Could you explain why 0.0023040 gram is a measurement having 5 significant figure?

The number 0.0023040 has 5 significant figures because zeros (0s) before other numbers do not count as being significant. So the only significant figures are "23040". If you write the number in scientific notation, it's easier to tell how many figures are significant. 2.3040 x 10-3 has 5 significant figures.

### When determining the number of significant digits in a measurement all zero are significant?

If your question was 'what is 216 to one significant figure', the answer would be 2. This is because the two means two hundred. If your number was 0.216 and you had to round it to one significant figure it would also be 2, but if your number is 0.203 and you had to round it to two significant figures you would say 20 this is because you only count the zeros as significant figures…

### How many significant figures are in temperatures?

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…

### How does conversion factors affect the number of significant figures in a problem?

If the conversion factor is exact, then the number of significant figures in the answer is the same as the number of significant figures in the original number. If the conversion factor is an approximation, then the number of significant figures in the result is the lesser of this number and the number of significant figures in the original number.

### How many significant figures are in the number 1039.520?

Seven (7) significant figures. All digits left of the decimal to the right of any leading zeros. All digits to the right. The zero is counted because it is significant that the measurement was taken to that level of precision. The full measurement may have been 1039.5201, .5202, etc. For whatever reason, the measurement was taken to 3 digits to the right of the decimal.
