Kilo

[ebee]

1 Kilo = 1000
1 Kilobyte = 1024 bytes
therefore is 43008 bytes 42Kb or 43Kb ?

PS If any one doubts it the egg came before the chicken

 

[LoveRocket]

technically speaking, 1kB = 1000bytes, 1kiB = 1024 bytes....

Quite right:

Thanks,
I knew someone would clear that up.

It's amazing how many folk had no idea (hadn't spotted the little i) including me.
Now it makes sense

 

[Monkeh]

Nobody spotted it because nobody used it (and MS still refuse to because it would 'confuse' people).

The Kilo is a decimal measurement but with computers we use binary measurement so 2, 4, 8, 16, 32, 64, 128, 256, 512, 1024 and so closest to Kilo is 1024.

There are a few things which don't seem to line up with decimal system it is suppose to be easier and work in 10's so how does one get 4.2 Joules in a calorie? Or a Kilo = 9.8 Newtons. Was not the 32 poundals in a pound and 32 pounds in a slug much easier and also worked well with binary system.

Now I pumped up my tyres to 32 pounds per square inch not one slug per square inch so how come conversion uses Newtons?

One Nautical mile = one second of movement around the earth seems to make sense but seems the French got it wrong with Kilometre and anyway shouldn't a replacement be based on Radians not degrees?

Seems we just have to remember 749W = 1 Horse Power = Energy to lift 1 pound 550 foot in 1 second or something like that. Long time since I used Fletcher's Trolley.

For 0.83 pence (2 pennies) I would get rid of Decimal!!!

Would these be the same people who MS thought would be confused by the correct colour names magenta and cyan and that therefore they should rename them pink and turquoise?

 

[Monkeh]

Probably.

... so how does one get 4.2 Joules in a calorie?

Because the calorie is not an SI unit, but the joule is.
Why on earth would anyone expect them to be x10 multiples of each other?

Or a Kilo = 9.8 Newtons.

Well, 1 kg doesn't equal 9.8 N, does it?
The kilogram is a measure of mass (m), the newton a measure of force (F). They are linked by acceleration (a).
In the context you mean, the acceleration acting on a mass is due to gravity, and is equal to 9.8 ms^-2.

F = ma, so 1kg x 9.8 ms^-2 = 9.8 N

Basic physics.

 

[LoveRocket]

Eric, simply move to a slightly more massive planet where a due to gravity is exactly 10m/s/s and your worries will be over!

Or at the very least replaced with more pressing ones.

twe 9.81 when I was a lad.
Has it lost a bit?

Might have!

It's actually defined as 9.80665 ms^-2: http://physics.nist.gov/cgi-bin/cuu/Value?gn|search_for=gravity

I'm sure it has got stronger.

What else explains that it's harder climbing stairs and ladders these days, and more of an effort to get up from kneeling on the floor etc?

When we were at college we were told 9.81 and we were not allowed to round it to 10 for easy peasy (pre calculators being common)

You lads today get to round it to 9.8 (or ban is correct, by his reasoning I thin he is correct).

We were told it varied in different parts of tworld, some parts of tworld were a tadd more and some parts of tworld less
