Width of a 27 1-1/4 inch tyre

Hello : 

Would anyone know the width in mm of a 27 1-1/4 inch tyre ?

Is it 1.25 inches equivalent in mm ( ie 31.75mm ) - Or some other number ?

I am trying to “compare” the ride quality of a bike I used to ride eons ago on similar road conditions that I will once again ride on with a contemporary bicycle that I will purchase shortly. 

I do understand this is not an equal comparison for the different frame materials ( perhaps even tyre technology etc. ), but as I mainly have the previous experience to work with I am trying to arrive at some “base-line” in terms of ride-quality I can expect based on tyre width.

This is important as I have narrowed down my choice to 2 frames - One that can accommodate 28C & the other to 32C & hope to “match” the earlier ride experience.

I also appreciate that this is just one variable among a few others that will be considered as I make the final decision on the optimal bicycle to purchase. 

Hope some of you have an answer to my above question. 

Thanks in advance.
