Metal Weight & Length Calc

Estimate metal weight from your dimensions and density, or calculate equal piece lengths from a total target mass. A focused metal weight calculator for bars, plates and tubes, with useful Free calculations and an optional lifetime Pro upgrade for repeat work.

FREE CALCULATOR
• Six ideal profiles: solid round, square, flat bar, plate, round tube and rectangular tube.
• Weight from length: total mass, mass per piece and mass per unit length.
• Length from TOTAL target mass and quantity: length per equal piece and total length.
• Explicit units for each dimension: mm, cm, m, in and ft. Mass in g, kg or lb.
• Editable density, with approximate steel, aluminum and stainless-steel starting presets.
• One retained calculator draft, plus light, dark and system themes.
• Core arithmetic works offline, without a PatchMedia account or an arbitrary calculation quota.

OPTIONAL LIFETIME PRO
One non-consumable Google Play purchase, not a subscription. Google Play shows the local price and availability.
• Organize named jobs, scenarios and notes.
• Save density and source snapshots with the measurements used for each estimate.
• Copy and edit alternatives without replacing the original scenario.
• Compare 2–4 saved scenarios, including their dimensions and assumptions.
• Estimate procurement mass and cost using your entered allowance and prices.
• Export CSV job sheets, share text, and back up or restore saved work with JSON.

Existing saved records remain readable, exportable and deletable if Pro access is unavailable. Creating or editing Pro records and restoring a library require active Pro access. Purchase restoration is handled separately by Google Play; a JSON file does not contain paid ownership.

TRANSPARENT ESTIMATES
Results describe ideal geometry using the measurements and density you enter. Preset densities are approximate. Real stock, corners, tolerances and material density can differ. Check supplier specifications or weigh stock when exact mass matters.

This app does not provide structural design, certification, standard-section catalogues, pipe schedules, cutting/nesting plans, PDF output, live metal prices, currency conversion or supplier quotations. Entered costs are estimates based on your own assumptions.

LOCAL WORK AND CHOSEN FILES
Measurements and saved jobs stay in private device storage during normal use. No ads, PatchMedia analytics, app account or automatic cloud synchronization. You choose export/share destinations; files are plaintext and a chosen provider may synchronize them. Google Play manages purchases, and its Billing SDK can send technical billing diagnostics, including before a purchase.
