Therefore, the conversion results are different with different densities. Generally, according to the density of water, the density of water is 1g/cm3, which is brought 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 cmn.
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.
Gram, the unit of mass, symbol g. One gram is the mass of18×14074481c-12 atoms. The weight of one gram is approximately equivalent to the weight of one cubic centimeter of water at room temperature.
Kilogram is the unit of mass, and mass is equivalent to how "heavy" a thing is every day. However, quality is actually a property with "inertia"; In other words, an object will tend to maintain its existing speed without external force.
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 under 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.
