About This Converter
This density converter supports 10 units spanning metric, imperial, and specialty systems. Every calculation passes through a kg/m³ base, so results are precise whether you are comparing material densities in g/cm³, fluid densities in lb/gal, or engineering values in slug/ft³. It is a handy tool for chemists, engineers, brewers, and students.
FAQ
What is the density of water?
Pure water at 4 °C has a density of 1,000 kg/m³, which equals 1 g/cm³, 1 kg/L, or about 62.43 lb/ft³. Water's density is often used as a reference point for comparing other materials.
What is the difference between kg/m³ and g/cm³?
Both are metric density units. 1 g/cm³ = 1,000 kg/m³. Scientists and material-data sheets often use g/cm³ because common solids and liquids fall in the convenient 0.5 – 20 range, while kg/m³ is the official SI unit used in engineering calculations.
What is a slug per cubic foot?
A slug/ft³ is the imperial density unit consistent with the slug mass unit. 1 slug/ft³ = 515.379 kg/m³. It is used in US aerospace and fluid-mechanics calculations where forces are in pounds-force and lengths in feet.
How do I convert lb/gal to kg/L?
Multiply the lb/gal (US) value by 0.119826 to get kg/L, or simply enter the value here and read the kg/L tile. For example, water is about 8.345 lb/gal ≈ 1 kg/L.
