Significant Figures Quiz This online quiz is intended to give you extra practice in counting significant figures ("sig figs") in decimal and scientific notation as well as simple arithmetic problems. For example: log (210^5) = 5.301029995663981 - you should round this figure to 5.3. Following the rules noted above, we can calculate sig figs by hand or by using the significant figures counter. From physics category, we recommend you to see posts about Elastic Potential Energy. To learn more about rounding significant figures see our This calculator was originally developed by Quentin Truong, and expanded by the team at The Calculator Site. So if you only have one significant figure then you'd have say $7\%$ or $7\times10^1\%$. Sig Fig Calculator - Significant Figures Calculator There are a lot of rules regarding the figures. I learn simpler ways to solve and can check that my computations are correct. To avert repetitive figures that are not significant, you can round the given number. converting decimals to fractions. We are not to be held responsible for any resulting damages from proper or improper use of the service. Answer: .
