1 ml is equal to 1 g, one kilogram is 0.5 kg, and 1 kg is 1000 g, so 1 kg =0.5* 1000=500 g.

Milliliter is a commonly used unit of volume, while gram belongs to the international common unit of mass. How many grams is one milliliter? It usually needs to be calculated by a formula, and it is related to density.

The conversion formula of milliliter and gram is: mass-density * volume. According to the density of water, water density 1g/cm3, then the volume of 1g water is equal to 1g divided by 1g/cm3, and the result is 1cm3, 1 cm3 =/kloc-0. Different units can't be converted directly, so the conversion of milliliters and grams needs to be converted according to mass-density multiplied by volume.

Therefore, the conversion results are different with different densities. Generally, according to the density of water, the density of water is 1g/cm3. Substituting into the above formula, that is, the volume of 1g is equal to 1g/cm3 divided by 1g/cm3, and the result is 1cm3, while 1 cmn3.

1l = 1000 ml 1000 ml = 1 000 cm31000 ml =1cubic decimeter;

1 ml = 1 cc;

1 ml liquid water = 1 cubic centimeter liquid water;

1 ml The weight of liquid water at 4 degrees Celsius is 1 g;

1 ml = 1 cm3.

When an object with a mass of one kilogram is subjected to a force of one Newton, it will get an acceleration of one meter per square second (about one tenth of the acceleration of the earth's gravity).

The weight of a substance depends entirely on the local gravitational intensity, while the mass is constant (assuming that the mass does not move relative to the observer at relativistic speed).

Accordingly, astronauts in microgravity can lift objects in the space capsule without any effort; Because objects are "weightless". However, an object still retains its mass under micro-gravity, and astronauts need to exert ten times the force to accelerate an object with ten times the mass at the same acceleration.

Density is widely used in scientific calculation. According to its related formula, it can not only be used to identify all kinds of materials, but also calculate the related volume of complex modeling objects and the volume of liquids. In addition, density is also related to buoyancy, and it can also be used to judge the solid and hollow of an object and calculate the density of an unknown liquid.

Density also plays an important role in real life. According to the different densities, the densities of some drinks can be identified, so as to prevent them from falsifying the product quality. Because of the different properties of materials, foamed plastics are used as fillers in the transportation of some fragile items to prevent them from breaking.
