⚖️ Density Calculator
Density is mass divided by volume — the property that decides whether something floats or sinks. Enter mass in grams and volume in cubic centimeters.
Water's density (1 g/cm³) is the reference: anything denser sinks, anything less dense floats.
How to use this calculator
Enter an object's mass in grams and its volume in cubic centimeters to get its density in g per cubic cm and kg per cubic m.
- Weigh the object and enter the Mass in grams.
- Measure or compute its volume and enter it in cubic cm.
- The density appears instantly.
- Compare against 1 g per cubic cm, the density of water.
Frequently asked questions
What formula does the Density Calculator use?
Density equals mass divided by volume. The kg per cubic meter figure is the same value times 1000.
Can you give a worked example?
200 grams in 50 cubic centimeters gives a density of 4 g per cubic cm, which is 4000 kg per cubic meter.
How do I find an irregular object's volume?
Use water displacement: submerge it in a graduated container and read how much the water level rises. That rise is the volume.
What does the result tell me?
Whether it floats or sinks in water. Anything denser than 1 g per cubic cm sinks; anything less dense floats.
