Thank you sir for helping sirn but you misunderstood me.
I want to enter outerdiameter in cm, corediameter in cm and tickness in mm or micron and then calculate the lenght in meter.
Metric only, not a conversion.
If the diameters are entered in centimetres , and the thickness in millimetres , the result in metres is given in the attached file.

Hello Sir,

I have stumbled across this post and wondering if you can help. There is a spreadsheet attached with a layout to achieve the same result as above, but I can't work out how to adjust the formulas to output the right result.

The goal is to enter 2 dimensions and have formulas spit out 3 results depending on the edge thickness. Outer diameter in A14, Inner diameter in B14 will give results based on the material thickness.


Thanks to anyone who can solve my problem.
