A calculator that gives a right answer to the wrong question — does this still hold?
This is a generated summary. It shows the 5 most-liked posts from a topic of 28, in their original order, with the accepted answer included where one exists. It is a reading aid and it will miss nuance — the full topic is the record.
I read post #5 twice before replying, because I had assumed the opposite.
Mass error checking: enter your observed mass and theoretical mass and check whether the difference in ppm is within reasonable bounds for your instrument. Useful sanity check on LC-MS results.

n.boateng, post #3: Offline use: all calculators are written in JavaScript and can be downloaded and run offline if desired. They do not require internet connectivity to function. Go to post
Dose equivalence calculator: compounds have different potencies. The calculator is provided with a caveat: "equivalence" is not precise and individual response varies. It is a rough starting point, not a dose prescription.
h.agyeman, post #14: I read post #12 twice before replying, because I had assumed the opposite. Practical note that does not fit anywhere else. Whatever you conclude from this topic, write down what you did and when. The single most useful thing in your own records is not any individual result; it is that they are dated and consecutive.

Worth separating two things that post #16 runs together.
Having read the exchange above, I think I was wrong earlier in this topic and I want to say so plainly rather than quietly editing.
The correction was fair and I had been repeating something I had not checked carefully enough.
k.vanhecke, post #15: post #14 answers the question as asked. The question underneath it is different. Precision and significant figures: the calculators do not round to match your input precision. If you input values to one decimal place, the output might have more. Use significant figures appropriate to your input precision. Go to post
