Pounds per Cubic Foot Formula:
| From: | To: |
Pounds per cubic foot (pcf) is a unit of density that measures how much mass (in pounds) is contained in a given volume (one cubic foot). It's commonly used in construction, engineering, and materials science to describe the density of various materials.
The calculator uses the simple density formula:
Where:
Explanation: The calculation divides the total weight by the total volume to determine how densely packed the material is.
Details: Knowing material density is crucial for structural calculations, shipping weights, material selection, and quality control in manufacturing processes.
Tips: Enter weight in pounds and volume in cubic feet. Both values must be greater than zero. For accurate results, measure weight and volume carefully.
Q1: What's the difference between lb/ft³ and kg/m³?
A: 1 lb/ft³ equals approximately 16.0185 kg/m³. The kg/m³ unit is more common in metric system countries.
Q2: What are typical density values for common materials?
A: Water is about 62.4 lb/ft³, concrete 140-150 lb/ft³, steel 490 lb/ft³, and wood varies from 20-65 lb/ft³ depending on type.
Q3: How do I convert volume from inches to cubic feet?
A: Divide cubic inches by 1728 (since 12×12×12 = 1728 cubic inches in a cubic foot).
Q4: When would I need to calculate lb/ft³?
A: Common uses include calculating shipping weights, determining structural loads, comparing material properties, and quality control.
Q5: Can this be used for liquids as well as solids?
A: Yes, the density calculation works for any material - solids, liquids, or granular substances - as long as you can measure its weight and volume.
