# one cubic meter volume of water weighs how many kilograms?

### 12 Answers

- Anonymous1 decade agoBest answer
1 cubic metre = 1 m * 1 m * 1 m = 100 cm * 100 cm * 100 cm = 1,000,000 cc

1 cc of water weighs 1 gm

so, 1 cubic metre water weighs 1,000,000 gm = 1,000 kg = 1 metric tonne

This answer will depend on the density of the water that is used. According to Wikipedia the density of Water is 1000 kg/m^3. The equation for density is as follows: Density=Mass/Volume Multiply both sides by volume gives us the following equation Mass=Density*Volume. Given: Volume=1 cubic foot Density of Water=1000 kg/m^3 You most likely want how many lbs of water you need; thus we need to convert the Density of water from kg/m^3 to lbs/ft^3 Thus using an online conversion: 1 kilogram/cubic meter = 0.062 427 962 pound/cubic foot 1000kg/m^3= 62.43 lb/ft^3 Thus finally Mass=Density*Volume Mass=62.43 * 1 Mass=62.43 lbs approximate! Now since your designing it you want to design over 25% so therefore design for 78.04 lbs. Worry about the pressure on the sides more when designing this system.

1 cubic cm. of water is equivalent to 1 kilogram of water. So one cubic meter of water is 1,000,000 kgs.

1 1/4 * 2.2. One pint of water weighs a pound and a quarter.

It ways a tonne.

1 cubic centimeter (1cc) is the same as 1mL and you know that does not weigh 1kg. 1 cubic meter = 1,000kg.
