Steel Calculators & Shop Tools

Practical calculations for bar weight, machining stock, right triangles and unit conversions. Built for steel buyers, machine shops, fabricators and the order desk.

Steel Weight Calculator

Calculate estimated weight per piece and total weight for carbon and alloy steel bar.

Material condition

Bar shape

Diameter

Decimals or fractions accepted, such as 2.1875 or 2 3/16.

Cut length

Number of pieces

Enter the bar dimensions, then select Calculate Weight.

Estimating note. Results use a nominal density of 0.2836 lb/in³ for carbon and alloy steel. Hot rolled round weight includes an adjustable estimating allowance; actual dimensions, mill tolerances, and shipped weights can vary. This tool does not provide pricing or inventory availability.

Round Bar & Shop Geometry

Find the round stock needed to machine a square or rectangle, then solve common right triangle measurements.

Minimum Round for a Finished Square or Rectangle

For a finished 4" × 4" square, the theoretical minimum round diameter is 5.657" before any machining allowance.

Machining reminder. The calculated diameter is a geometric minimum, not a guarantee that a nominal stock size will clean up. Allow for material tolerances, straightness, surface condition, and the machining process. Confirm available sizes with Vanguard Steel.

Maximum Square from Round Bar

Right Triangle Calculator

Enter exactly two known measurements. Angle X is opposite leg A; C is the hypotenuse.

Force & Pressure Converters

Convert equivalent engineering units without mixing force and pressure.

Force

Pressure & Stress

Unit distinction. N/mm² is a pressure or stress unit and equals 1 MPa. N·mm is a torque or moment unit and cannot be converted directly to PSI.
