Do you really expect to buy carpet that fits room sizes exactly?

If you buy 'off a roll', yes, because you can measure the exact width.
The problem being, that most carpet suppliers will only have swatches for you to choose from, with no idea of the actual delivered width, due to the +/- tolerances. You might be lucky & get one which is a + width, but more often a -, which means wasting money on a wider carpet, or hoping the fitter can stretch it to fit. Not sure what the tolerances I have been quoted, but seem to remember its quite a lot.
 
Many building products reman made to imperial sizes but the industry uses metric equivalent measurements.
Steel beams of H section for example are imperial but we have for decades referred to them bu their metric serial size and weight in kg/m . We have never adopted the equivalent european sections.
The internal dimensions of a room in a house are rarely an exact measure regardless of whether the original setting out was in imperial or metric. Houses are not built to a great level of precision and never have been.

Well, you may say that, but none of B&Q's/etc doors would fit any of my internals when I changed them.
 
Litres per engine hour seems more appropriate units for the boat rather than mpg.

Never understood why people think any measurement without distance is useful. Only with distance do you know what is an efficient engine speed and how that might change dependent on the conditions. Also allows you to compare efficiency of boats.
 
You can tell the end of season looms and winter is close lol. ;) :D

Every tidal river and sea trip I make near my base in the UK the access to harbours is dictated by a tidal window.
Time for the journey is therefore something I always need to calculate.
Tidal flows can be significant on the river /estuary and this does significantly affect journey time at any given boat speed through the water.
If we are with the tide our fuel use is much reduced compared to the sometimes unavoidable consequences of travelling against the tide.
Fuel use for that journey is therefore easily estimated from the estimated hours run at speeds through the water rather than mpg.

For areas with little or no tidal flow I can see a simpler calculation may be sufficient.
 
Blame the builder or possibly the building regs for that. Not the metric system of measurement.

No, the houses were built during a period of metrication, which was subsequently dumped, so the B&Q's of the world stock for the majority of 'standard sizes'. The doors I had to buy, were much more expensive than those standard ones being sold back then, although same design/construction.
