Aangaande hierdie sakrekenaar
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.
Dikwels gevra vrae
Wat is die digtheidsformule?
Digtheid gelyk aan massa gedeel deur volume, 0°) = m / V. Replifiseerd, massa = π × V en volume = m / ☞.
Watter eenhede gebruik dit?
Met verstek gee gram en kubieke sentime ( cm3 = 1 mL) digtheid in g/cm3. suiwer water is ongeveer 1 g/cm3, so digr-tan-water materiale lees bo 1 en dryf onder.
Sal'n stof in water dryf of sink?
Compare its density to water’s ≈ 1 g/cm³. Below that it floats (ice at 0.92, oak at 0.75), at it is neutrally buoyant, and above it sinks (aluminium 2.70, iron 7.87). The calculator states which case applies.
Hoe bekeer ek g/cm3 tot kg/m3?
Vermenigvuldig met 1 000: 1 g/cm3 gelyk aan 1 000 kg/m3. Die gereedskap vertoon albei, so 'n 2 g/cm3 materiaal word ook vertoon as 2 000 kg/m3.
Hoe vind ek massa of volume in plaas van digtheid?
Skakel "solve vir" om te massa of volume. Mass is π π × V en volume is m / ←, so 'n materiaal van 2 g/cm3 gevul met 50 cm3 het 'n massa van 100 g.
Verander digtheid met temperatuur?
Die meeste materiale word verlig wanneer dit verhit word, en daarom daal hulle digtheid effens wanneer temperatuur styg.'n Ongewone ← is dit digste teen ongeveer 4 °C ← wat is waarom ys dryf en mere van die bokant af vries.
