Steel round is a popular metal product used in construction, engineering, and industry. Its weight depends on the diameter and length, and calculations are regulated by GOST 2590-88. In the article, you will find a formula, table, and online calculator for quick determination of the rod's mass.

GOST 2590-88: Standards for Hot-Rolled Round Bars

According to GOST 2590-88, steel round bars (hot-rolled) are manufactured with diameters ranging from 5 to 270 mm. The standard defines permissible deviations in dimensions, curvature, and other parameters. For example, for a diameter of 16 mm, the maximum deviation is ±0.3 mm. These norms ensure accuracy in weight calculations.

Formula for Calculating the Weight of 1 Meter of Steel Rod

The weight of 1 meter of a round bar is calculated using the formula:

Weight (kg) = (Diameter² × 0.00617)

where the diameter is taken in millimeters.

10 mm Steel Round: 10² × 0.00617 = 0.617 kg/m.
Weight of 16 mm Steel Round: 16² × 0.00617 = 1.58 kg/m.
18 mm Steel Round: 18² × 0.00617 ≈ 2.0 kg/m.

Table of Steel Round Weights by Diameter

For popular diameters, use the provided data:

Diameter (mm)	Weight 1 meter (kg)
10	0.617
16	1.58
18	2.0

For non-standard sizes, it is more convenient to use the online steel round weight calculator rather than searching for values in the table.

How to Use the Calculator?

Specify the diameter of the steel round in mm (e.g., 16, 18, 10).
Enter the length of the rod in meters.
Indicate the metal type of the rod.
Get the result: weight of 1 rod or the total weight of the batch.

Conclusion

Use the online steel round weight calculator for quick and accurate calculations. This method will save time and help avoid errors when ordering metal products!
