They tell you what level of precision you can expect from measurements that are made using that instrument.
Estimated
The degree of accuracy of the measuring instrument.
estimated
There are two significant figures in 0.025.
The greater the number of significant figures, the greater the precision. Each significant figure increases the precision by a factor of ten. For example pi = 3.14 is accurate to 3 significant figures, while pi = 3.14159 with 6 significant figures is a more accurate representation.
There are 2 significant figures in this number.
The least count of a measuring instrument is the smallest value that can be measured with the instrument. It determines the precision of the measurement. Significant figures, on the other hand, are the digits in a number that carry meaning about the precision of the measurement. The number of significant figures in a measurement is related to the least count of the instrument used to make that measurement.
Estimated
The measurement of the keyword "length" typically has an infinite number of significant figures, as it can vary in precision depending on the context and measuring instrument used.
Significant figures in a number are all the non-zero digits and zeros between them that are significant for the precision of the measurement. To determine the significant figures in a number, count all the non-zero digits and any zeros between them. Trailing zeros after a decimal point are also significant figures.
The degree of accuracy of the measuring instrument.
4 significant figures.
estimated
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.
There are 4 significant figures in 0.0032. Seems to be only 2 significant figures in this number.
There are 3 significant figures in 94.2.
3 significant figures.
