Formula
mass ÷ volume
Result unit: kg/m³

Density ρ = Mass / Volume. Mass in kg after engine conversion (no change), volume in m³ (L × 0.001). Result directly in kg/m³.

Introduction

Calculate density (mass per unit volume) using ρ = m/V. Density is a fundamental material property used in buoyancy, fluid mechanics, and material identification.

How This Calculator Works

Density ρ = Mass / Volume. Mass in kg after engine conversion (no change), volume in m³ (L × 0.001). Result directly in kg/m³.

Step-by-step process:

  1. Enter your input values in the calculator above
  2. The engine converts all inputs to SI base units (meters, kg, Pa)
  3. The formula is evaluated: mass / volume
  4. Result is formatted with the appropriate unit and precision

Calculation Example

10 kg of water occupying 10 liters has density 1000 kg/m³.

Inputs: mass=10, volume=10
Result: 1000 kg/m³

Engineering Applications

  • •Material identification
  • •Buoyancy calculation
  • •Fluid mechanics
  • •Quality control

Frequently Asked Questions

What is the formula for density?

Density = Mass / Volume (ρ = m/V). SI units: kg/m³. Common alternative: g/cm³ (1 g/cm³ = 1000 kg/m³).

What is the density of water?

Water density is 1000 kg/m³ at 4°C. At room temperature it is approximately 998 kg/m³.

How do I convert density between kg/m³ and lb/ft³?

1 kg/m³ = 0.06243 lb/ft³. For example, water at 1000 kg/m³ = 62.43 lb/ft³. Conversely, multiply lb/ft³ by 16.018 to get kg/m³.
