Stainless Steel Density Used
The calculator uses a density value of:
ρ=7.93 g/cm3
This density represents a common average value for many stainless steel grades.
Understanding the Calculation Process
Weight calculation requires two major steps:
- Calculate Volume
- Calculate Weight
Formula for Stainless Steel Plate Weight
For a rectangular plate or sheet:
V=L×W×T
Where:
- V = Volume
- L = Length
- W = Width
- T = Thickness
Because dimensions are entered in millimeters, the calculator converts the result into cubic centimeters.
Formula for Round Bar Volume
Round bars are cylindrical in shape.
The volume is calculated using:
V=πr2h
r
h
Abase=πr2≈28.27
V=πr2h≈226.19r = 3.0h = 8.0
Where:
- V = Volume
- r = Radius
- h = Length
Radius is half of the diameter.
Formula for Weight Calculation
Once volume is known, weight is calculated using:
Weight=Volume×Density
Since density is measured in g/cm³, the result is converted into kilograms.
Example 1: Stainless Steel Plate Weight
Suppose you have a stainless steel sheet with:
| Measurement | Value |
|---|---|
| Length | 2000 mm |
| Width | 1000 mm |
| Thickness | 5 mm |
Step 1: Calculate Volume
Volume:
2000 × 1000 × 5 ÷ 1000
Volume = 10,000 cm³
Step 2: Calculate Weight
Weight:
10,000 × 7.93
= 79,300 grams
Step 3: Convert to Kilograms
79,300 ÷ 1000
= 79.3 kg
Result:
- Volume: 10,000 cm³
- Weight: 79.3 kg
Example 2: Stainless Steel Round Bar Weight
Suppose you have:
| Measurement | Value |
|---|---|
| Length | 1500 mm |
| Diameter | 50 mm |
Step 1: Radius
Radius:
50 ÷ 2 = 25 mm
Step 2: Calculate Volume
Volume:
π × 25² × 1500 ÷ 1000
≈ 2945.24 cm³
Step 3: Calculate Weight
Weight:
2945.24 × 7.93
≈ 23,353.75 grams
Step 4: Convert to Kilograms
≈ 23.35 kg
Result:
- Volume: 2945.24 cm³
- Weight: 23.35 kg
