Calculate the weight of a steel plate in 5 seconds
Summary: What is the formula for calculating steel plate weight? Theoretical weight calculation formula for stainless steel plates; weight calculation method for 304 stainless steel plates; how much does one square meter of 3mm-thick 304 stainless steel plate weigh? A 3mm steel plate weighs 23.79 kg per square meter, and a 4mm steel plate weighs 31.72 kg per square meter; weight calculation formula for stainless steel plates.
A quick method for calculating steel plate weight:
一. Formula for Calculating the Weight of a Rectangular Steel Plate
Weight of rectangular steel plate = Thickness × Width × Length × Density
Example: A 304-grade steel plate with a thickness of 3 mm, a width of 1.5 m, and a length of 6 m.
The weight of the plate is: 3 × 1.5 × 6 × 7.93 = 214.11 kg.
Note: The unit for thickness is millimeters (mm); the units for width and length are meters (m); the unit for density is grams per cubic centimeter (g/cm³); and the unit for weight is kilograms (kg).
二. Formula for Calculating the Weight of a Circular Steel Plate
Weight of circular steel plate = Thickness × Area × Density (where Area = π × r², and r is the radius of the circle)
Example: A circular steel plate made of 304-grade steel, 3 mm thick, with a diameter of 1.2 meters.
Its weight is calculated as follows: 3 × 3.14 × 0.6 × 0.6 × 7.93 = 26.89 kg.
三. Formula for Calculating the Weight of an Annular Steel Plate
Weight of the ring = Weight of the outer circle – Weight of the inner circle. The simplified calculation formula is: Thickness × π × (r1² – r2²) × Density (where r1 is the outer radius and r2 is the inner radius).
Example: A ring-shaped 304 steel plate with a thickness of 3 mm, an outer diameter of 1.2 m, and an inner diameter of 1 m.
Its weight is: 3 × 3.14 × (0.6² – 0.5²) × 7.93 ≈ 8.22 kg.
四. Densities of Various Stainless Steel Grades
201/304/304L/321: 7.93 g/cm³
316/2205: 8 g/cm³
