Significant Figures (Sig Fig) Calculator The online significant figures calculator helps you to converts any number or expression into a new number with desired amount of significant figures (sig figs). Sometimes significant figures are 'lost' while performing calculations. Antilogarithm (n^x.y) uses the power's number of decimals (mantissa) as the result's number of significant figures. When doing math in chemistry, you need to follow some rules to make sure that your sums, differences, products, and quotients honestly reflect the amount of precision present in the original measurements. so that the resulant value does not appear to be more accurate than the equipment used to make the measurement allows. Rules for counting significant figures also apply to numbers written in scientific notation. Being that one of the addends has only 2 decimal places, the final resultant value contains 2 decimal places. Which figure has the least amount of decimal places?

You perform the calculation then round your solution to the correct number of significant figures. The resultant value in proper significant figures will be automatically computed and displayed. Khan Academy is a 501(c)(3) nonprofit organization. For example, consider the formula for diameter of a circle, d = 2r, where diameter is twice the length of the radius. Exact physical and mathematical constants and defined conversion factors (π, 1 inch = 2.54cm, 1kg = 1000g) and integer coefficients (like the 2 in “2 πr”) have an infinite number of significant figures. Oh, and let me make this clear. All non zero numbers are significant (meaning they count as sig figs) 613 has three sig figs 123456 has six sig figs 2. if we have the numbers 254.6 and 234.789 being added, the final resultant will have 1 decimal place, since one of the addends only contains one decimal place. Rounding Significant Figures Calculator. For example, if 12.2, 3.66, 214.39 and 2.472 are to be added, the answer would be 232.7 because the number with least decimal places is 12.2 meaning the answer should be rounded to 0.1 … So our final answer can only have three significant figures.
