It works based on four key inputs:
- Length (mm)
- Width (mm)
- Thickness (mm)
- Density (g/cm³)
By combining these values, the calculator determines how much space the metal occupies and how heavy it is.
This is especially useful for engineers, fabricators, students, and professionals who work with metals like steel, aluminum, copper, iron, and alloys.

Step 5: Click Calculate
Press the calculate button to instantly get:
- Metal Volume (cm³)
- Metal Weight (kg)
Step 6: Reset (Optional)
If you want to perform a new calculation, simply reset the tool and enter new values.
Formula Used in Metal Calculator
Understanding the formula helps you better interpret the results.
1. Volume Calculation
The first step is calculating volume:
V=L×W×T
Where:
- V = Volume (mm³)
- L = Length (mm)
- W = Width (mm)
- T = Thickness (mm)
Convert mm³ to cm³:
Since 1 cm³ = 1000 mm³:
Vcm3=1000Vmm3
2. Weight Calculation
Once volume in cm³ is known, weight is calculated using density:
Weight=Volume×Density
To convert grams to kilograms:
Weightkg=1000Vcm3×Density
Important Unit Conversions
Understanding units is critical for accurate results:
| Measurement | Unit Used | Conversion |
|---|---|---|
| Length | mm | 10 mm = 1 cm |
| Width | mm | 10 mm = 1 cm |
| Thickness | mm | 10 mm = 1 cm |
| Volume | cm³ | 1000 mm³ = 1 cm³ |
| Weight | kg | 1000 g = 1 kg |
Example Calculation
Let’s understand with a real-world example.
Given Values:
- Length = 500 mm
- Width = 200 mm
- Thickness = 10 mm
- Density = 7.85 g/cm³ (Steel)
Step 1: Volume
Volume in mm³:
500 × 200 × 10 = 1,000,000 mm³
Convert to cm³:
1,000,000 ÷ 1000 = 1000 cm³
Step 2: Weight
Weight in grams:
1000 × 7.85 = 7850 g
Convert to kg:
7850 ÷ 1000 = 7.85 kg
Final Result:
- Volume = 1000 cm³
- Weight = 7.85 kg
