Density measures how much mass is packed into a given volume: ρ = m / V. Rearranged, the mass of an object is m = ρ × V and the volume it occupies is V = m / ρ. This calculator lets you solve for any one of the three, entering the other two in whatever units you have — grams, kilograms, pounds and ounces for mass, and cm³/mL, litres or m³ for volume — and returns the density in both g/cm³ and the SI unit kg/m³ (1 g/cm³ = 1,000 kg/m³).
As a worked example, a 100 g object occupying 50 cm³ has a density of 100 / 50 = 2 g/cm³ (2,000 kg/m³) — a bit less dense than aluminium. Because pure water is very close to 1 g/cm³, the calculator also tells you whether a material floats: anything below about 1 g/cm³ floats, anything above sinks, and something right at 1 g/cm³ is neutrally buoyant. A built-in table lists common densities for comparison — ice 0.92, oak 0.75, water 1.00, aluminium 2.70, iron 7.87, lead 11.34 and gold 19.32 g/cm³.
Density is used to identify materials, check the purity of metals and gemstones, work out whether an object will float or sink, convert between the mass and volume of fuels and liquids, and calculate the load a structure or vessel must carry. Because it is an intensive property — independent of the amount of material — a small sample gives the same density as a large one, which is what makes it such a reliable fingerprint for a substance.
Imibuzo ebuzwa kaningi
Yini ifomu lokuqina?
Ubukhulu bulingana nesisindo esihlukaniswe ngobukhulu, ρ = m / V. Kulungiswe kabusha, isisindo = ρ × V nobukhulu = m / ρ.
Yini amayunithi asetshenziswa yilokhu?
Ngokungajwayelekile, amagramu namasentimitha ayi-1 (1 cm³ = 1 mL) anikeza ukuphakama kwengcindezi nge-g/cm³. Umanzi ahlanzekile alingana ne-1 g/cm³, ngakho-ke ama-denser-than-water materials afunda phezulu 1 futhi ahamba ngezansi.
Ingabe izinto zizohamba noma zizowela emanzini?
Uthelekisa ubukhulu bayo nowomanzi ≈ 1 g/cm³. Engezansi ihamba (ikhephu ku 0.92, i-oak ku 0.75), ekugcineni ihamba ngokukhululekile, futhi phezulu ihamba phezulu (i-aluminium 2.70, insimbi 7.87). I-calculator ichaza ukuthi iyiphi inkinga esebenza.
Ngiguqula kanjani i-g/cm³ ibe yi-kg/m³?
Ukuphindaphinda nge 1,000: 1 g/cm³ ilingana ne 1,000 kg/m³. Ithuluzi libonisa zombili, ngakho 2 g/cm³ izinto zibonisa njenge 2,000 kg/m³.
Ngiyithola kanjani isisindo noma ivolumu endaweni yokugcwala?
Shintsha "ukulungisa" ube yisisindo noma umthamo. Isisindo yi ρ × V futhi umthamo yi m / ρ, ngakho-ke impahla ye 2 g/cm³ egcwalisa 50 cm³ inesisindo se 100 g.
Ingabe ukuphakama komhlaba kushintsha ngokushintsha kwezinga lokushisa?
Ngokuncane, yebo. Ama-materials amaningi akhula uma epholile, ngakho-ke ukuphakama kwabo kukhuphuka kancane uma izinga lokushisa likhuphuka. Umanzi awujwayelekile — ukuphakama kwayo kukhuphuka ku-4 °C — ngakho-ke i-ice ihamba futhi ama-lake abanda kusuka phezulu kuya phansi.
