Understanding the relationship between mass and volume is essential in many fields, including chemistry, physics, engineering, cooking, and industrial production. Whether you’re working with grams, milliliters, or kilograms per cubic meter, converting mass to volume helps you understand the space a material occupies.
Mass to Volume Calculator
⚖️ What Is Mass to Volume Conversion?
Mass refers to how much matter an object contains, usually measured in grams (g), kilograms (kg), or pounds (lb).
Volume refers to how much space that matter occupies, usually measured in milliliters (mL), liters (L), or cubic meters (m³).
To convert between them, we need density – a property of the material that links mass and volume.
📘 Mass to Volume Formula
Here’s the basic formula used for the calculation:
plaintextCopyEditVolume = Mass ÷ Density Where:
- Volume is in cubic units (e.g., mL, L, m³)
- Mass is in weight units (e.g., g, kg)
- Density is in units like g/mL, kg/m³, etc.
🧪 How to Use the Mass to Volume Calculator
This tool works in three simple steps:
1. Enter the Mass
Input the value and choose the appropriate unit (e.g., grams, kilograms, ounces).
2. Enter the Density
Use the correct density value and select its unit (e.g., g/mL, kg/L, lb/ft³).
3. Get the Volume
The tool will automatically calculate and show the volume in your desired unit (e.g., mL, L, m³).
Some calculators may allow you to select materials from a dropdown, automatically populating standard densities.
🧮 Example Calculations
Example 1 – Water in Everyday Units
Mass = 500 g
Density of Water = 1 g/mL
plaintextCopyEditVolume = 500 g ÷ 1 g/mL = 500 mL So, 500 grams of water equals 500 milliliters.
Example 2 – Aluminum
Mass = 2.7 kg
Density of Aluminum = 2.7 g/cm³ = 2700 kg/m³
Convert mass to kg: already in kg
Density = 2700 kg/m³
plaintextCopyEditVolume = 2.7 kg ÷ 2700 kg/m³ = 0.001 m³ = 1 liter Example 3 – Olive Oil
Mass = 150 g
Density of Olive Oil ≈ 0.92 g/mL
plaintextCopyEditVolume = 150 g ÷ 0.92 g/mL ≈ 163.04 mL 📦 Real-World Applications

🌡️ What Is Density?
Density = Mass ÷ Volume
So, the rearranged formula becomes:
Volume = Mass ÷ Density
Densities vary by material. For example:
| Substance | Density (g/mL) |
|---|---|
| Water | 1.00 |
| Milk | ~1.03 |
| Olive Oil | ~0.92 |
| Gold | 19.32 |
| Air (at sea level) | 0.001225 |
Using the right density ensures accuracy in volume calculations.
🧠 Mass to Volume vs. Volume to Mass
They are inverse operations:
- Mass to Volume: Used when you know how much something weighs and want to know how much space it takes.
- Volume to Mass: Used when you know how much space is occupied and want to find its mass.
