Does 1litre of water equal to 1kg?

Wikipedia says:
One litre of liquid water has a mass of almost exactly one kilogram, because the kilogram was originally defined in 1795 as the mass of one cubic decimetre of water at the temperature of melting ice (0 °C). Subsequent redefinitions of the metre and kilogram mean that this relationship is no longer exact.[ |

"In liquid state yes. In gaz (steam) state no.
What about ice?????????????????????????????????????????????????????????????????????"
Perhaps counter intuitively, the density of ice is less than liquid water - hence, when it forms, it floats on the surface. |

Who would win... a sun made of ice v's a regular, garden variety sun of fire? |

I believe a litre of ice would weight less than a litre of water. Because of the difference of density. If you fill a 1litre bottle with water and put it in the freezer it will break suggesting the same quantity of matter occupies more space in solid form than in liquid form.
So if you consider the same volume (1 litre) you will have less matter in solid form hence it will weight less. |

"Yes, pretty much so - although the density of water (and other liquids of course) does vary ever so slightly with temperature. What prompted your question OP? "
Good. I was watching a utuber making their own weights, it was interesting  |

"I was thinking about this if it is the same or not or just a bit more? 
Why not just Google it and find out "
Far better to ask a bunch of randoms on a swinging site, than get the answer from a scientist who’s qualified in this field. |

"Yes. They correlate

Doing your weight loss maths shag ? and fat is less dense at .9 kg per litre
Just for fun , average 5 8 person , around 75 kg will have approx 1m2 of skin
For my calcs I value 10mm of fat below skin at 10 kg
Thus for a mm lost I aim for a 9000 cal deficit ish |

It is interesting with volume v the same weight |

Can't get a meet without verification but can't get verified without a meet . Go on be a devil and buck the trend I'm sure you will be pleasantly surprised |

"Simple answer is yes Good, it is interesting "
It is interesting yes as depends on the material.
For example 1 kg of concrete is equivalent to 0.42 litres, so all dependant in the density of the material |

A ton of feathers and a ton of lead weigh different. Or something.
I'm now wondering if wet concrete weighs differently to set concrete.
I need Pringles.
Good thread Shag!  |

So do you think that the scientific experts got it wrong, That due to the polar ice caps melting, the sea levels were supposed to rise.
They were only looking at mass. And they never took into consideration also, that the dispersion of the water world wide, would be absorbed by the increase in the oceans depth pressure increase.
Your thoughts. ! |

No they are correct
First geological records show low sea level whilst in full ice age
We appear to still be onward with the melting and the sea level rise is due to land glacier melting, and a small amount of thermal expansion |

1 Kn of feathers weigh the same as 1kn of lead

Haha Mavis, pass the Pringles
A ton of feathers is the same as a ton of lead.
However, wet concrete and set concrete will weigh differently, just like water and ice
A thread to get the mind boggling |

The increase in water level was nowhere near sufficient to compress the water at sea-floor level. Water is very incompressible.
Wikipedia says: “Between 1900 and 2016, the sea level rose by 16–21 cm (6.3–8.3 in)”. The Mariana Trench is about 7 MILES beneath the surface of the sea, so an extra foot will make no measurable difference to the density at the bottom of the 7-mile water column.

Ty and yes yw. I also find it interesting the volume v the same weight |

A flaccid cock to an erect cock ?
If my memory in my iphone is now full is it now heavier than when I first purchased it ? Is a flat battery heavier than a fully charged one?
If one of your car tyres is heavier flat or inflated ? |

In science class at school 1cm cubed of water is equivalent to 1ml so yeah.
And also it takes precisely 1joule of energy to heat a cm3 of water 1 degree. |

Erect is full of blood, so heavier.
Your Iphone’s weight will not change as its memory fills because nothing is being added. It’s just the magnetic properties of the memory material being changed.
There are different types of battery. The old lead-acid car batteries lost weight as they were charged because the gave-off water. We had to top them up. Modern sealed batteries don’t change their weights when they are charged. The electrons flow around the circuits, so that there’s always virtually the same number in the cell.
Inflated car tyres are heavier because air has been added, and air isn’t weightless. Scuba divers can find out how full their air tanks are by weighing them.
An old chestnut: “A van is transporting 100 live birds in the back. Is the van heavier when all of the birds are sitting on their perches, and lighter when they are all flying about?”

"Sounds like a QI question"
Ironically, it's true. There was a statement on a recent QI, which was that new scientific research disproves the original assessment of 1Kg and it's true weight.
That's all I remember. |

For normal purposes, yes, 1 litre of water weighs 1 kg. It was defined that way when the SI system was set up.
If you want accuracy to several decimal places other factors like temperature, salinity, chemical composition have to be taken into account.
The QI discussion was about the so called triple point, where water exists as ice, liquid water and vapour all at the same time. |

Weight or mass? 1Kg is nit a weoght |
