Formula: kg/L = oz/in³ × 1.73
Multiply any oz/in³ value by 1.73 to get kg/L.
Reverse: oz/in³ = kg/L × 0.578

1 oz/in³ = 1.73 kg/L.
Water = 1,000 kg/m³ = 1 g/cm³ = 1 kg/L = 62.4 lb/ft³ = 0.0361 lb/in³.
Multiply result by 0.578 to recover the original oz/in³ value.
Compares material densities to optimize weight-to-strength ratios in product design.
Calculates dead loads from material densities for structural design in kg/m³ and lb/ft³.
Selects lightweight materials (aluminum, titanium, composites) based on density in g/cm³ or lb/in³.
Measures crude oil and drilling fluid density in kg/m³ or lb/ft³ for reservoir engineering.
Measures soil and rock bulk density in t/m³ for foundation and slope stability analysis.
Uses density in g/cm³ for solution concentration, specific gravity, and process design calculations.
Ounces per cubic inch (oz/in³) is used in some US manufacturing and specialty applications. One oz/in³ = 1/16 lb/in³ = 1,729.99 kg/m³. It provides finer resolution than lb/in³ for lower-density materials.
oz/in³ appears in some US military and industrial specifications for plastics, composites, and lightweight materials. Water density = 0.578 oz/in³. Aluminum = 1.56 oz/in³. It bridges the gap between lb/in³ (too coarse) and g/cm³ (metric).
Interesting fact: The ounce as a weight unit traces back to the Roman uncia (1/12 of a pound), though the modern avoirdupois ounce (1/16 pound) became standard in medieval English trade. The oz/in³ density unit combines two historical measurement artifacts.
Kilograms per liter (kg/L) is numerically identical to g/cm³ and 1,000 kg/m³. It is widely used in the fuel industry — diesel density is about 0.82–0.85 kg/L, petrol 0.71–0.77 kg/L — and in the food and beverage industry.
Fuel efficiency calculations require density in kg/L to convert between volume (liters sold) and mass (kilograms of fuel burned). Honey density is about 1.36 kg/L; olive oil 0.91 kg/L; seawater 1.025 kg/L.
Interesting fact: Liquid hydrogen, the most energy-dense rocket fuel by mass, has a density of only 0.071 kg/L — about 14 times less dense than water, requiring enormous tanks despite its high energy content.
Converting oz/in³ to kg/L is common in materials science, engineering, and manufacturing. SI units (kg/m³, g/cm³) are standard in scientific and metric engineering contexts, while Imperial units (lb/ft³, lb/in³) are used in US construction and aerospace. Water at 4°C = 0.578 oz/in³ = 1 kg/L — a universal anchor for density comparisons.
Exact factor: 1 oz/in³ = 1.73 kg/L. Reverse: 1 kg/L = 0.578 oz/in³.
All conversions use IEEE 754 double-precision arithmetic, accurate to at least 8 significant figures.
