# Density Calculator

## Description
Calculate density, mass, or volume given the other two values. Supports multiple units and includes a common materials density reference table.

## Features
- Solve for density, mass, or volume
- Unit conversions for mass (g, kg, lb, oz), volume (cm³, m³, L, mL, ft³, gal), and density (g/cm³, kg/m³, lb/ft³, kg/L)
- Real-time reactive calculations
- Common material densities reference table

## How to Use
1. Select what you want to solve for (Density, Mass, or Volume)
2. Enter the two known values with their units
3. View the calculated result and all unit conversions

## Formulas
- Density: ρ = m ÷ V
- Mass: m = ρ × V
- Volume: V = m ÷ ρ

## Supported Units
- Mass: g, kg, lb, oz
- Volume: cm³, m³, L, mL, ft³, gal
- Density: g/cm³, kg/m³, lb/ft³, kg/L
