Absolutely remarkable, and somewhat shocking, that a company like Boeing is (was?) using imperial measurement and not metric.  Metric is far more precise and easy to use.

US units are still widely used in America. They are as precise as metric units.

I find myself using imperial for rough measurements but metric for anything precise.

 

That's not because metric is more precise, in fact imperial is just as precise, It's as you say, metric is easier, more convenient.

 

Some claim that we in the UK use the metric system. Actually that's a joke. We use both the metric system and imperial. We check our weight in stones and pounds, have speed limits in MPH, speedometers in MPH. We use feet, inches, yards, metres, centimetres, millimetres and fractions of an inch...

 

You could say they tried to metricate us but it got stalled half way, so we ended up using both.

I maintain several Hawker business jets, whose airframes were built in the UK, and then completed in the US. Much of the hardware is imperial, but there are a smattering of bolts and fasteners in the aircraft that use the rather obscure "British Standard" system of sizes, which complicates things.

 

We do have a set of British Standard spanners, which were quite difficult to come by - I think we had to special order them from a supplier in the UK.

I've gotten used to using imperial now, very odd to get my head around to begin with but working in the aviation industry its no problem, it becomes the normal thing!

Try telling someone in Europe you have a slight fever! "I've just checked my temperature it's 99"

The person to whom you have just said that is now on the way to hospital with a heart attack!
