Tentang Konverter massa jenis
Density is mass per volume, so each unit is a mass unit divided by a volume unit, held here as kilograms per cubic metre. The metric units differ by powers of 1,000 (1 g/cm³ = 1 g/mL = 1 kg/L = 1,000 kg/m³), and the imperial ones follow from the exact pound and foot: 1 lb/ft³ = 16.0185 kg/m³.
The default converts 1 g/cm³, close to the density of water, to 62.428 lb/ft³. Engineers use lb/ft³ (pcf) for soils and concrete, drillers use lb/gal (ppg) for drilling mud, and materials data sheets use g/cm³.
Density changes with temperature, and the converter only changes units. Pure water is densest near 4 °C at 999.97 kg/m³ and is 998.2 kg/m³ at 20 °C, so “1 g/cm³ for water” is right to within 0.2%.

Pertanyaan
How do I convert g/cm³ to kg/m³?
Multiply by 1,000. A cubic metre holds 10⁶ cubic centimetres and a kilogram is 1,000 grams, so 1 g/cm³ = 1,000 kg/m³. Aluminium at 2.70 g/cm³ is 2,700 kg/m³, and steel at about 7.85 g/cm³ is 7,850 kg/m³. g/mL and kg/L are the same size as g/cm³.
What is specific gravity?
The ratio of a substance's density to the density of water, so it has no unit. Referenced to water at 4 °C (999.97 kg/m³), specific gravity equals the density in g/cm³ to within 0.003%: a liquid of 0.80 g/cm³ has a specific gravity of 0.80. Other references, such as water at 60 °F, change the fourth significant digit.
How do I convert lb/ft³ to kg/m³?
Multiply by 16.0185. A pound is 0.45359237 kg and a cubic foot 0.028316846592 m³, both exact, so 1 lb/ft³ = 16.01846337 kg/m³. Normal-weight concrete at about 150 lb/ft³ is about 2,400 kg/m³, and 1,000 kg/m³ is 62.43 lb/ft³.
What does ppg mean for drilling mud?
Pounds per US gallon, the density unit of oilfield drilling fluids. 1 lb/gal is 119.826 kg/m³, so fresh water at 20 °C is 8.33 ppg and a 12 ppg mud is 1,438 kg/m³, or 1.44 g/cm³. Mud weight sets the pressure the fluid column exerts at the bottom of the well.
Is the density of water exactly 1 g/cm³?
No, but close. Pure water peaks at 999.97 kg/m³ near 4 °C and is 998.2 kg/m³ at 20 °C. The gram was first defined in 1795 as the mass of 1 cm³ of water, and from 1901 to 1964 the litre was defined as the volume of 1 kg of water, which is why the numbers nearly coincide.
Seberapa akurat “Konverter massa jenis”?
Akurasi bergantung pada masukan dan asumsi metode. Aritmetika desimal memakai 50 digit signifikan, tetapi perkiraan, metode numerik dan data sumber bisa kurang presisi; pembulatan yang ditampilkan tidak menghilangkan batasan itu. Contoh penyelesaian yang diperiksa dengan sumber independen: 4. Misalnya, “1 g/cm³ in lb/ft³” diperiksa dengan 1000 kg/m³ ÷ (0.45359237 kg / 0.028316846592 m³) = 14158423296/226796185 (Python 3.8 fractions from the legal definitions).
