1. What is Stone Density Conversion?

Definition: This calculator converts the density of stone from kilograms per cubic meter (kg/m³) to pounds per cubic foot (lb/ft³).

Purpose: It helps construction professionals and material scientists work with density measurements in different unit systems.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ \rho = \rho_{kg/m³} \times 0.062428 \]

Where:

\( \rho \) — Density in pounds per cubic foot (lb/ft³)
\( \rho_{kg/m³} \) — Density in kilograms per cubic meter (kg/m³)

Explanation: The conversion factor 0.062428 comes from the relationship between kg/m³ and lb/ft³ (1 kg/m³ ≈ 0.062428 lb/ft³).

3. Typical Stone Density Values

Details: Most natural stones have densities between 137–187 lb/ft³ (2200–3000 kg/m³). This includes common construction materials like granite, limestone, and sandstone.

4. Using the Calculator

Tips: Simply enter the density value in kg/m³ and the calculator will provide the equivalent in lb/ft³.

5. Frequently Asked Questions (FAQ)

Q1: Why convert between these units?
A: Different industries use different measurement systems - metric (kg/m³) in most countries and imperial (lb/ft³) in the US.

Q2: What's the exact conversion factor?
A: 1 kg/m³ = 0.062427960576145 lb/ft³ (we use 0.062428 for practical calculations).

Q3: How does moisture affect stone density?
A: Wet stone can be 5-10% denser than dry stone due to water filling pores.

Q4: What's the density of common stones?
A: Granite ~168 lb/ft³, Limestone ~160 lb/ft³, Sandstone ~150 lb/ft³, Marble ~170 lb/ft³.

Q5: How is stone density measured?
A: Typically by weighing a known volume of stone or using specialized density measurement tools.
