10g iirc, as 10cm3 = 1kg

nope, 1.000 cm3 = 1 kg (given the right conditions).

Just remember this:
An engines with a displacement of 2 liters also has a displacement of 2.000 cm3.
So 1.000 cm3 of H20 = 1 Liter of H20
100 cm3 = 0,1 liters
10 cm3 = 0,01 liters

1 cm3 = 1 ml = 1 g

doh!

thanks

just had a major brain fart early in the morning. I was thinking of a cube with 10cm side, weird... like i said, early hours

[LeonOfTheDead]

no probs mate, yesterday I put the tv remote in the fridge

10g iirc, as 10cm3 = 1kg

I thought one liter weighed 1kg.

fresh water, yes, petrol, no...

Of course we need to point out that 1.000 cm3 is written using the European "." to indicate a thousands divider, not a decimal point. I read 1,000=1000 and 1.000=1 because for what ever reasons the world didn't seem to standardize on the "." vs ","

BTW, I checked 1floz is equal to ~0.8oz (perhaps exactly but I'm not sure). I checked by converting 1floz to ml, then assuming 1ml weighs 1gram then converting grams to oz. I got 0.8 but I'm not sure if stuff was rounded by Google in the conversion.

(Note: All values from memory, Google might have said 1floz weighs 6.374 hogsheads (the US style decimal separator, not 6374).)

Good point there.
TBH, in Italy we don't use the "." to write "1000", and we use the "," to write "0,1".
I thought over teh interweb the "1.000=1000" was a common assumption though .

[culver]

I just checked Google in that regard. Of course in the US and for US centric websites we would assume 1.100 to be 1+1/10. I asked Google to convert some numbers. Here is what I got:
"1,10 lbs = ? kg" returns "1,10 pounds = 0,498951607 kilograms"
So it was clearly read as 1+1/10.
but,
"1,100 lbs = ? kg" returns "1100 pounds = 498.951607 kilograms"
so it was read as 1100lbs.

"1.100 lbs = ? kg" returns "
1.10000 pounds = 0.498951607 kilograms"

and
"1.10 lbs = ? kg" returns "1.10 pounds = 0.498951607 kilograms"

It seems that Google will handle a "," as the decimal marker but only when it clearly can't assume it to be a thousands marker. It doesn't seem to ever assume a "." is a thousands marker. Of course Google is a US company trying to take over... er... serve the world.

1 cm3 = 1 ml = 1 g

1ml = 1 cm^3, so where are you getting 1 cm^3 = 1 kg?

I'm confused.

Are you using a different denomination?

We just cleared that up.. in Europe, the . is a thousands separator.

1000 ml = 1 liter = 1000 cm3 = 1 kg = 1000 g

^^^ with caveats and assuming approximations

Each time they improve laser time standards it goes and screws the SI units "perfection".

so there is still hope that they improve the laser time standards to such an extent that the mile and the lbs will become the best SI units.....
About the "european/continental" way of writing things, yes, the "dot" is the separator for 1000s (and and starts to become important for numbers over 1 million, just to assist in discerning the number) and the "comma" for decimals, always to be applied.

Ok, thanks.

1000 ml = 1 liter = 1000 cm3 = 1 kg = 1000 g

Yup, I know that part, but thanks anyway

Well yeah, obviously, but you can't do that with the American system at all wihtout some serious conversions. Temperature plays a big part, but if you want to quickly guestimate, go right ahead. Besides, if you do care, density at a certain temperature and air pressure can quickly be looked up.

[culver]

For those over in Europe, why is it that Top Gear's UK website refers to a "1.6L" motor instead of a "1,6L"? Is the "," vs "." an English speaking vs X speaking thing? Which languages, countries etc used "," for the decimal?
