ABC Wednesday - K is for kilo

K is for kilo, but what is kilo? Kilo comes from Greek and means one thousand - 1000 - 10 raised to the third power and so on. One of the most common uses is a as a prefix in the the word kilogram - the standard for Mass. According to the international body BIPM,

The kilogram is the unit of mass; it is equal to the mass of the international prototype of the kilogram.
Now, it is obvious to everybody that these two weights shown here cannot be the prototype. The prototype is kept in a vault with six copies at BIPM in Paris and and can be seen to the left. The prototype is also made out of a platinum/iridium alloy which my weights most definitely are not. In fact, they are each only half a kilo (five hekograms) each, but 1/2 plus 1/2 make 1 - right?

The real reason is of course that I couldn't lay my hands on a one kilo weight in time for the picture.




PS For more about ABC Wednesday, please visit Mrs. Nesbitt's Place. It is well worth the effort.

At least you haven't lost your sense of humor!

When I saw BIPM I thought you meant BMI
Transplanted persons body mass index is increasing. At least here.
Great idea for ABCW

Nice to see that many of ABCW players are here still athough many need education in HTML and reading rules

Aha.........
Hubby is a precision engineer, so measurements are often to the nearest 1000/th of a mm....guess the weights here would not measure up to callibration? LOL!

Truls said...

Better to see two half kilos that all the extra kilos we all carry around!

See my ABC wednesday here.

Liz said...

That's interesting. I had never thought of the 'prototype' before but I suppose it must be a standard

Anne-Berit said...

Great K-choice from you,and intresting reading:o)

weights and measures is a contentious issue in the UK with folk prefering their pounds and ounces.

Personally I tend to buy by quantity [two rashers of bacon, eight small potatos, half a cucumber &c] rather than weight.

Beautiful pictures for an interesting, but difficult subject ...
I suppose that the museum you visited is "le Musée des Arts et métiers", à Paris ?
I have enjoyed your funny wit on my blog !

An interesting K and nice photo. I tought of the kilo's too, but I didn't know how I cud explain it;) Nice work, Arne!

Wonderful K selection. I would have never thought of that one. I was having a hard time with "K" until I came upon the clock.

Gordon said...

I knew about the prototype in Paris but had not seen it; thank you.

Dirty Knees said...

Thanks, Rune. I know I'll learn something when I visit your blog and I appreciate that.

We are officially metric here in Canada but many older people resist it as much as possible, ;-) However, school kids for years have only been taught the metric system -- so if we want to remain current we MUST learn too.

Personally, I think metric makes more sense than the Imperial.

My K post is not educational ;-)

Interesting "K" post.

I was really struggling trying to find a "K" to post. Last night I thought about keys and that just did not excite me. I was just staring down at my computer and started laughing when I realized I was staring at a KEYBOARD. Then I thought, DUMB ME, I have a toy piano and real piano in the house too with keyboards on them.

As for the redecorating on my blog, I thought it might help my blog. For some reason for about a week now my comments are no where as many as in the past. I thought wondering if I made someone mad and I cannot think of anything wrong I have done so I thought maybe it has to do with the appearance of my blog. Just trying to make it look more inviting for people to visit.

The post and all the comments are great. Oh to be so clever. Love your 1/2 kilos....

Autumn said...

Very interesting. I am horrible at math so I have never learned how to transfer anything into Kilo.

Jan said...

Interesting post. We don't deal with Kilos, here, much. It's always good to learn.

Hanne Cecilie said...

Interesting K and you have done a great job with the photographing.

quintarantino said...

Great photo and good info.

Katney said...

Your ABC posts are always fun and informative. I guess you couldn't put your hands on a kilo of platinum either, eh?

leslie said...

In Canada, we're officially metric, yet everywhere we still use imperial. For example, babies are always X lbs X ozs, we measure our height in feet and inches, etc. We buy our milk in kilos but our butter in lbs. I was forced to learn the metric system better when I went back to teaching, but still have trouble with it.

Interesting information!

Look my KILO in my blog!!

Canada has used the metric system for over thirty years but many people are resistant to change from the imperial measures.
I myself prefer the metric system.
If that Mamiya camera has screwmount lenses, with an adapter, the can be used with the Pentax cameras

Neva said...

At least you are honest!!1 A very good choice for "K".

Old Wom Tigley said...

Great K post and nice little weights.. 1/2 +1/2= 1.. ha!

Helena said...

I had trouble thinking up something for K and I'm amazed at what others are thinking of!

Diana said...

excellent K! thanks for the learning lesson, it was really interesting. I never knew original kilo's or halfies were saved anywhere!

Sharon said...

This is an interesting K post. The photos were good!

kRiZ cPEc said...

thanks for the lesson, :)

AVCR8TEUR said...

Nice macro photos of the half kilo weights. We are still stuck in the English units or U.S. Customary Units of measure.

Thank you for the comment about my kayak photo.

Berit said...

Kjempeflott K. Skulle gjerne vært eiger av slike!

Digital Flower Pictures said...

Nice post. You have been posting some great pictures.

starnitesky said...

Of course K for kilo, I didn't think of that. Interesting to read about the prototype, it didn't occur to me there was such a thing.

kml said...

The most original post for K!

VP said...

How inventive Runee - great post :)
