In mathematics, "2sf" stands for "two significant figures." It refers to the practice of rounding a number so that it retains only the first two digits that carry meaningful information. For example, the number 0.00456 rounded to two significant figures would be 0.0046. This notation is often used in scientific calculations to indicate the precision of measurements.
