We have just had a loft conversion and the building inspector now needs to know if the steel beam put in our through lounge some 15 years ago is the measurement as given above, but I can't understand what this is. Can it be converted to feet and inches or not

yes it can be done. The 203 x 133 are I hope in millimetres.This would be 8 inch x 5 1/4 inch if you measure the beam it should be somewhere close.The weight of 30kg would depend upon the thickness of the metal in the different parts of the beam.A steel stockist could give you the thickness of the different weights per metre so you could compare the millimetre thickness given to the inch measure. To convert millimetre to inch divide the number of millimetres by 25.4 if you know any engineers they should be able to assist.Not being at work I do not have the information to hand.If your local library has "KEMPS" year book in its reference section that could help.Kellys directory would give you steel stockists, if you cannot find one locally.The info is probably on the internet somewhere.Can investigate further for you if you cannot resolve.

The exact dimensions of a 203 x 133 x 30 kg/m beam are given at the reference below near the bottom of the table

In old units the beam is 8" x 5,1/4" and weighs 20 lb/ft.

are you sure that's right ? well if the section is imperial and you want to convert into english, then just divide the metric by 25.4, which would be 7.992(8.00)x 5.236(5 1/4)x 1.181or x1.488 for kg/m which would be 302.064 x 197.904 x 44.64

i cant believe the quantity of stupid those who placed up those dumb issues on right here late at evening. its late and they procrastinate till the stunning minute, posting this dumb crap on right here. perchance pay interest at school or benefit worry-free experience truly of slacking off and also you could learn this basic basic stuff. that's like first grade math, branch and multiplication. make sure it out your self .

im hopeless with anything mathematical but i think ive found something of use to you try here http://www.vhfman.freeuk.com/tables/conversion.html
only other thing i can suggest is ask an architect, hope im of some use to you
