At average gravity on Earth (conventionally, g = 9.80665 m/s²), a kilogram mass exerts a force of about 9.8 newtons. An average-sized apple exerts about one newton of force, which we measure as the apple's weight.^[4]

1 N = 0.10197 kg × 9.80665 m/s²    (0.10197 kg = 101.97 g)

So Khriss gave a good approximation (water is 1kg/litre)

these questions are fairly common - in Bing etc type in 25N = kg

will return25 newtons = 2.54929053 kilograms-force

so truncate the answer to 2.55 kg (approx 2litres plus 550ml water) if you want to go all sciency you can weigh the container and deduct one ml of water for each gram the bottle etc weighs

On Jupiter you wouldnt even be able to pick it up ?

Unless your using heavy water, but personally I would not be drinking it.

the fundamental forces are all much of a muchness - is gravity that different to the force that lifts the Maglev?

if you really believe it all came out of absolutely nothing, a vacuum, once upon a time
