Formula
length × width × thickness × density
Result unit: kg

Weight = L × W × T × ρ. SS304 = 7930 kg/m³, SS316 = 8000 kg/m³ (slightly heavier due to molybdenum).

Introduction

Calculate the weight of stainless steel sheets and plates. SS304 density is 7930 kg/m³; SS316 is 8000 kg/m³ due to molybdenum alloying. Stainless is about 1% heavier than carbon steel.

How This Calculator Works

Weight = L × W × T × ρ. SS304 = 7930 kg/m³, SS316 = 8000 kg/m³ (slightly heavier due to molybdenum).

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: length * width * thickness * density
  4. Result is formatted with the appropriate unit and precision

Calculation Example

A 1000mm × 500mm × 3mm 304 stainless steel sheet weighs 11.9 kg.

Inputs: length=1000, width=500, thickness=3, density=7930
Result: 11.9 kg

Unit Conversion for Stainless Steel Weight

**Weight units**

- 1 kg = 2.20462 lb

- 1 tonne = 1000 kg

- 1 lb = 0.4536 kg

**Length units**

- 1 m = 3.28084 ft

- 1 inch = 25.4 mm

**Density units**

- 1 kg/m³ = 0.06243 lb/ft³

Stainless steel density is about 7900-8000 kg/m³ (304: 7930, 316: 7990). Weight = density × volume; keep all dimensions in the same unit system before computing.

Frequently Asked Questions

What is the density difference between 304 and 316?

SS304: 7930 kg/m³. SS316: 8000 kg/m³. The difference (~0.9%) is due to molybdenum in 316.

Is stainless heavier than carbon steel?

Yes, slightly. Carbon steel = 7850 kg/m³ vs 7930 for 304 (about 1% heavier).

How do I convert weight between kg and lb?

1 kg = 2.20462 lb. For example, a 50 kg stainless plate weighs 110.2 lb. Convert dimensions to consistent units before computing.
