I'm writing an article about tips and tricks for Sig Fig. I found some on google but I need more.

I want to write also about an online calculator. Please suggest.

Hello,

I was a math teacher. My first priority was always to teach students tricks about math.

Yes, some online calculators are reliable like sig fig calculator on calculators.tech. Actually, the reason I like this calculator also describes which rules are applied to calculate significant figures of your entered number.

I would treat that calculator with caution.

 

You need to understand significant figures.

 

Say I said. This piece of timber is 2.5 metres long and I want that expressed to 4 significant figures.

 

I put it in your Sig fig calc and I get  2.500 m

 

This is incorrect.  2.5 has 2 significant figures, it cannot be written to 4 significant figures.  The question is nonsense.

A nonsense answer is given to a nonsense question.
