3sf stands for "three significant figures," which is a way of expressing numbers with a specified level of precision. It indicates that only the first three digits that contribute to the accuracy of a number are considered, regardless of the decimal point. For example, the number 0.00456 would be expressed as 0.00456 in 3sf, while 1234 would be rounded to 1230 to maintain three significant figures. This notation is commonly used in scientific and mathematical contexts to convey the precision of measurements.
