Skytech Rolling Mill Pvt Ltd is renowned for its expertise in manufacturing and supplying an extensive range of Stainless Steel Round Bars. Understanding the intricacies of these bars, including their weight calculation, uses, and advantages, is crucial for various applications across industries. This article dives into the essential aspects of Stainless Steel Round Bars, emphasizing the weight calculation formulas and providing a comprehensive view of their significance.
A Round Bar Calculator, also known as a Round Bar Weight Calculator, is a tool used to determine the weight of round bars based on their dimensions and material density. This calculator helps manufacturers, suppliers, and customers accurately estimate the weight for efficient logistics and cost calculations.
Calculating the weight of an MS (mild steel) round bar involves a straightforward formula. The formula to determine the weight per meter of the round bar is: Weight (kg) = Diameter (mm)2 × 0.006165.
Here’s how it works: you take the diameter of the round bar in millimeters, square it, and then multiply by 0.006165 to get the weight in kilograms per meter. This coefficient (0.006165) is derived from the density of mild steel and the geometric properties of a round bar. For example, to calculate the 10mm round bar weight per meter, you would square 10 (which is 100) and then multiply by 0.006165, resulting in a weight of approximately 0.6165 kg per meter. Using this method, you can quickly determine the weight for various diameters using an ms round bar weight calculator or an ms round bar weight chart for easy reference.
Round bar weight calculation formula –
The theoretical weight of 1 meter of a round bar М is determined by the formula: М = L * ρу, where L is the length of the round bar; ρу – theoretical mass of 1 m of a round bar, calculated by its nominal dimensions: For steel density ρ = 7850 kg/m³: ρу = 0.0061654 * d2, (kg/m), where d is the circle diameter in mm.
Understanding the weight of round bars is crucial for various manufacturing, construction, and logistics applications. One of the most commonly used materials in round bars is mild steel (MS), and to ensure precise measurements, tools like the MS round bar weight per meter calculator are essential. This ms round bar weight calculator allows users to input the diameter and length of the round bar to obtain the exact weight, which is vital for planning and cost estimation. Additionally, having access to an MS round bar weight chart can simplify the process by providing quick reference weights for different sizes. For instance, knowing the 10mm round bar weight per meter helps determine the load capacity and material requirements for specific projects. These tools enhance efficiency and ensure accuracy in material handling and cost management.
A round bar weight chart displays the weight of round bars in kilograms (kg) per meter, pounds (lb) per foot, and correlates these weights to their diameters in millimeters (mm) for quick reference and calculation.

What is a Round Bar?
A Round Bar is a long, cylindrical metal bar stock with various industrial, commercial, and residential applications. It is available in different materials, including stainless steel, which is prized for its resistance to corrosion and oxidation. This makes it a popular choice in environments where durability and longevity are critical.
How to Calculate Bar Weight?
Calculating a bar’s weight, whether round, square, flat, or hexagonal, is crucial in various fields such as construction, manufacturing, and logistics. The weight is often necessary for cost estimation, transportation, and structural design calculations. The formula for calculating a bar’s weight varies slightly depending on its shape but generally follows a principle based on the material’s density and the bar’s volume.
General Formula for Bar Weight
The general formula to calculate the weight of a bar is:
Weight = Volume × Density
Where: Volume is the bar’s space, which depends on its shape and dimensions.
Density is the material’s mass per unit volume. Steel is typically around 7850 kg/m³ or 0.284 lb/in³.
Stainless Steel Round Bar Weight Calculation Formula
For a round bar, the volume can be found using the formula for the volume of a cylinder, πr²h, where r is the radius, and h is the height (or length of the bar). Therefore, the weight of a round bar in kilograms can be calculated as:
Weight (kg)=π×(Radius (m))2×Length (m)×Density (kg/ m³)
If the diameter is given, remember that the radius is half the diameter. For a round bar with a diameter in millimetres (mm), the formula adjusts to account for the unit conversion to meters (since density is in kg/m³):
Weight (kg)=10002π×(Diameter (mm)/2)2×Length (m)×Density (kg/ m³)
Example Calculation for a Round Stainless Steel Bar
Let’s calculate the weight of a stainless steel round bar with a diameter of 20 mm and a length of 2 meters. The density of stainless steel is approximately 7850 kg/m³.
Weight = π×(0.01m)²×2m×7850kg/ m³
Weight = 3.14×0.0001 m²×2 m×7850 kg/ m³Weight=3.14×0.0001m2×2m×7850kg/ m³
Weight = 1.57 kg Weight =1.57kg
This calculation gives you the weight of the round bar in kilograms. Similar principles apply to bars of other shapes, but different formulas for the volume are used based on the shape’s geometry.
