- How many sig figs do i use when making conversions
Homework Statement I have to do a bunch of problems such as converting meter to km and cups to mililiters etc How do i calculate sig figures for these problems for example i did 12 miles to kilometers 12 miles x 1 609 km 1mile = 19 308 km = 19 km ? do i leave the sig figs at
- How do we account for multiple sources of uncertainty in a measurement?
Do sigfig rules for addition and subtraction apply also to uncertainties? For the example above, would the uncertainty be + - 1 degrees celsius (retaining one sigfig only -- not using sigfig rules in uncertainty) or would it be + - 1 0 degrees celsius (retaining 2 sigfig 1 decimal place -- using sigfig decimal place rules in uncertainty)
- Logarithmic significant figures - Physics Forums
In most areas of science, being able to solve and report problems to the correct number of significant figures is necessary; but I'm having trouble finding a complete set of rules for significant figures when working with non-ideal power equations eg: I'm talking about equations requiring the
- Sig figs certainty in percent error calculation - Physics Forums
Normally, at least abstracting from the problem, after subtracting 1 95 from 1 87 for a difference of -0 08, the zeros would not be considered significant and we would consider this result to have one significant digit, but really, we have certainty about those zeros as values, correct?
- What are Significant Figures? A 5 Minute Introduction
Significant figures (commonly called "sig figs") are the number of figures (digits) included when rounding-off a number The rules about how to round-off are not entirely agreed upon

I want to convert celsius to Kelvin using 273 15 I have a temperature 22 5 C Then I want to find 1 T 273 15+22 5 = 295 7 since 22 5 has the least
- Question about sig figs and rounding: How to handle when there are 2 . . .
Hey I just started taking a physics course and I am a bit confused about sig figs and rounding My question is that if there are two parts to a physics problem and the latter part requires an answer from the first part, then do you use the sig fig rounded value or the calculated value For
