Some conventions are "50" has one sig fig (so your answer should round to 100) and "50." (note the decimal) is more precise. You should check with your instructor/textbook for what the conventions are. $\endgroup$ –

Then you would say the measurement is 1 × 10 − 6 g, which is one significant figure. Anything below that wouldn't be effectively measurable. So you don't get any significant figures from a zero measure. Share listview width autoWebNote that when doing a combined operation you keep track of sig figs according to order of operations, but never round until the end. For example: 870 + (.87 \* 8700) Here your first move is to multiply .87 by 8700, which yields 7569 with 2 sig figs (both .87 and 8700 have 2 sig figs and you were multiplying). You then add 7569 + 870 and get 8439. imp analyticsWebHow many significant figures does 0.400 have? 0.400 has 3 significant figures and 3 decimals. 0.400 rounded to 2 sig figs is 0.40, and to 1 sig figs is 0.4.
