oz/in³ to g/cm³ Converter
Convert ounces per cubic inch to grams per cubic centimeter — one oz/in³ is 1.73 g/cm³. Results update as you type; exact factors shown.
One ounce per cubic inch is 1.73 gram per cubic centimeter — see the exact factor, not a rounded rule of thumb.
How the oz/in³ to g/cm³ converter works
Density converts through kg/m³. 1 g/cm³ = 1 kg/L = 1,000 kg/m³ (water at 4 °C). 1 lb/ft³ = 16.0185 kg/m³ and 1 lb/US gal = 119.83 kg/m³. Concrete is about 2,400 kg/m³, steel 7,850 kg/m³, petrol about 740 kg/m³.
The US uses customary units (US gallon, short ton, °F) in daily life; NIST SP 811 gives the exact SI factors.

FAQFrequently asked questions about density conversion
How many g/cm³ is 1 oz/in³?
1.72999 g/cm³.
What is water in oz/in³?
0.578 oz/in³.
Where is this unit used?
Occasionally in US plastics and moulding specifications.
What is 4.5 oz/in³?
7.79 g/cm³ — about the density of steel.
Why so many density units?
Because each industry standardised on whatever its measuring equipment gave, and none of them ever changed.
