The significant figures calculator undertakes calculations with significant figures and works out how many significant figures (sig figs), i.e., digits, a number holds.
Simply input a number or mathematical expression, then click the "Calculate" button for the answer.
Operators and functions that are supported:Arithmetic operators: addition ( + ), subtraction ( - ), division ( / or ÷ ), multiplication ( * or × ) and exponent ( )Group symbols: ( )Functions: log n, ln nConstants: pi, eExact quantitiesIn calculating with sig figs one sometimes encounters quantities that are exact as opposed to having limited accuracy. You can enter an exact quantity by appending an # to end of the number; e.g. 3.2#. For instance, if you want to convert 3.00045 g sulfur to moles using sulfurs molecular weight of 32.06 g/mol you would use the following calculation:3.00045 / 32.06# = 0.0935886 mol sulfuras opposed to the calculation:3.00045 / 32.06 = 0.09359 mol sulfurwhere 32.06 is taken to onl...
