To quote Bill Bryson ("The road to Little Dribbling"):
'Of course they make sense,' the British person will sniff. 'Half a firkin is a jug, half a jug is a tot, half a tot is a titter, half a titter is a c**k-droplet. What's not logical about that?'
We have traces of funny units in the metric world, too, such as measuring thickness in grams. Plated silverware (not silver through) is usually referred to as "60 grams", but not until recently did I know the true meaning of the "60 grams": If 60 grams of silver is used to plate 24 pieces of cutlery, 12 forks and 12 (full size) spoons, then the silver layer has a thickness of 60 grams.
Earlier, cheaper silverware was only 40 grams. Some years of use might wear off the silver so the cutlery got brownish spots where the underlaying copper comes out. Today, 60 grams is the standard; that is enough to stand many years of wear.
None of my sources said a word about how many micrometers thick layer 60 grams of silver would make on 24 pieces. I was thinking of measuring the surface area of a spoon and a fork to get a rough idea (I know of no good way to measure the surface area exactly), but I never got around to it. If anyone around here knows the answer - how many micrometers is 60 grams? - I'd be happy if you would reveal it!
Religious freedom is the freedom to say that two plus two make five.

1) How are you @OriginalGriff ?
2) As of today I am officially an Inventor [pending] as we've just submitted a patent application with my scrawl on the bottom left.

Is it a patent for improved wedge bolts btw ?

Congratulations! I remember my first patent - I was "but it's so obvious - why didn't someone else do it first?"
I'm getting there - still miss her like crazy, and my sleep pattern is all over the place so my concentration is ... um ... poor and I get distracted very easily so I forget what I was doing. That's OK when you are holding a wooden spoon, but ceramic knives make it a lot riskier. I'm still not cooking properly as a result!

I wanted to mount a small safe with two wedge bolts that were supplied with it.
As usual the drill went everywhere when I tried to drill some holes in a concrete wall 
Did the bolts work as intended? of course not, they kept turning round as they were smooth on the outside.
Did any of the reviews on the website where I bought it mention this? of course not.
Had to replace the bolts with other ones before the safe could properly be attached.
I don't understand people who claim that they like DIY, sigh ...

Wrong drill bit type, size, or possibly just blunt?
Mark a center punch hole first (I use a Draper 13612 - it's spring tension adjustable, and doesn't need a hammer freeing up a second hand), then drill a pilot hole that is slightly smaller the screw diameter without the threads (for a "screw in device") or smallish compared to the final bit for push in ones.
Drill out the pilot to the final size for push in devices with a slightly small bit - you can "wiggle it" a bit to get the right size, but you can't add material back and concrete bits generally drill a little larger than you expect!
For concrete, carbide tips are a good choice, but make sure they are sharp - they can chip quite easily if you aren't careful with them, and a blunt drill will do more damage than you might think!

If I am not sure about the quality of the wall (or if I do am sure it is crap), then I drill first a hole with two sizes less than my target diameter.

If you do DIY right it's rewarding, if you get screwed up by tools and products you use it's annoying. End of the story.
"Pro tip" from my side, never use anything provided with the product and instead have dowels and screws in your toolbox that are good quality.

This is possibly the least understood rule of DIY - you must have a comprehensive supply of fixings, screws, dowels, bolts, you name it before you start.
Another tip - when boring holes in glass or ceramic tiles, using the hammer facility on your drill is counterproductive

And put a piece of tape across where you want to drill - the bit won't skate off into the distance then.

At least, not so much.
I usually put a cross of tape, like the cartoon sticking plaster, to get enough depth for the bit to grip and not skate, and use the drill really really slowly, just grinding the surface until there's a depression. Then you can up the speed. A little oily lubricant helps, one you've started. Turpentine is recommended for glass.
