Formula: kg/L = lb/ft³ × 0.01602
Multiply any lb/ft³ value by 0.01602 to get kg/L.
Reverse: lb/ft³ = kg/L × 62.43

1 lb/ft³ = 0.01602 kg/L.
Water = 1,000 kg/m³ = 1 g/cm³ = 1 kg/L = 62.4 lb/ft³ = 0.0361 lb/in³.
Multiply result by 62.43 to recover the original lb/ft³ 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.
Pounds per cubic foot (lb/ft³) is the standard density unit in US engineering and construction. One lb/ft³ equals approximately 16.018 kg/m³. It is used for structural materials, soil, insulation, and HVAC calculations in American practice.
Common lb/ft³ values: air = 0.0765 lb/ft³, water = 62.4 lb/ft³, concrete = 145–150 lb/ft³, structural steel = 490 lb/ft³, wood varies 20–50 lb/ft³. ASHRAE tables for HVAC use lb/ft³ for air and refrigerant densities.
Interesting fact: Aerogel, the world's least dense solid material, has a density of about 0.1–1 lb/ft³ (1.6–16 kg/m³). It is primarily composed of air and can support thousands of times its own weight.
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 lb/ft³ 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 = 62.43 lb/ft³ = 1 kg/L — a universal anchor for density comparisons.
Exact factor: 1 lb/ft³ = 0.01602 kg/L. Reverse: 1 kg/L = 62.43 lb/ft³.
All conversions use IEEE 754 double-precision arithmetic, accurate to at least 8 significant figures.
