Steel Weight & Cost Calculator
Weight of any cut length from your own dimensions — not a standard-section lookup.
V = L × W × TV = (π/4) × D² × LFree · No sign-up · No email wall
Shop floor sums, with the working shown.
Eight calculators we use ourselves — conveyor sizing, turning parameters, bend allowance, weights. Every one prints the formula with your numbers substituted in, so you can check it, copy it into a report, or argue with it. Each calculator has its own page, with the method and formulas written out in full.
Belt Conveyor Capacity & Power Calculator
Throughput and an indicative motor rating, from width, speed, trough angle, length and lift.
Q_v = A × v × 3600 (m³/h)Q_m = Q_v × ρ ÷ 1000 (TPH)Screw Conveyor Capacity & Power Calculator
Capacity and power from screw diameter, shaft diameter, pitch, speed and trough fill.
Q = 47.1 × (D² − d²) × P × n × λ × C (m³/h)P_H = Q × ρ × L × λ_m ÷ 367Bucket Elevator Capacity & Power Calculator
Capacity and motor rating from bucket size, pitch, speed, fill factor and lift.
n_b = v ÷ pQ_v = V_bucket × n_b × fill × 3600 ÷ 10⁶ (m³/h)CNC Turning Speed, Feed & Power Calculator
Spindle speed, feed rate, MRR, cutting force, power and theoretical Ra.
n = Vc × 1000 ÷ (π × D) (rpm)Vf = f × n (mm/min)Sheet Metal Bend Allowance & Tonnage Calculator
Bend allowance, deduction, developed flat length and the press tonnage to make the bend.
BA = (π ÷ 180) × A × (R + K × T)OSSB = tan(A ÷ 2) × (R + T)Drive Ratio, Speed & Torque Calculator
Pulley and gearbox ratio, output speed, shaft torque and drum surface speed.
i_p = D_driven ÷ D_driveri = i_p × i_gearboxUnit Converter & Tap Drill Chart
Eight unit families, plus ISO metric coarse tapping and clearance drill sizes.
