What It Does
Scrap Rate Calculator
Calculate material waste instantly.
Carbon & Emissions Calculator
Estimate emissions for steel, aluminium, copper, brass, bronze, and more.
Steel Grade & Weight Calculators
Convert grades, calculate weights, and solve common production calculations in seconds.
Metals Calculators
Free tools for metals manufacturers to calculate scrap, emissions, material weights, costs, steel grades, yield, and compliance in seconds. Built for shop floors to save time and reduce errors.
Scrap Rate Calculator
Standardise scrap calculations across your operation and get consistent scrap-rate and cost reports to support improvement work.
Metals Emissions Calculator
Find out exactly how much CO₂ your metal orders are generating. Covers steel, aluminium (with regional grid factors), copper, copper-nickel, and brass/bronze alloys. Enter the material, weight and process, and stop guessing when sustainability reporting comes round.
Business Case Calculator
Build a business case that actually gets sign-off. Cost and benefit breakdown, exportable as PDF or a shareable link, so the people holding the budget can’t say they didn’t understand it.
Steel Grade Converter
Quickly convert between steel grade naming conventions and equivalents to help match materials and specifications.
Metal Weight Calculator
Calculate the mass of common metal shapes and profiles for 12 metal types, including steel, stainless, aluminium, copper, copper-nickel (Cu-Ni), and aluminium-bronze (Al-Bronze), with results in kg, lbs, and linear weight (kg/m and lb/ft). Round tube now supports NPS/Schedule, DN/Standard, and Copper Type K/L/M/DWV pipe lookup modes alongside manual OD/wall entry. For reinforcing bar, select round bar and enter the nominal diameter (H10, H12, H16, H20, H25, H32, H40) to get the weight per metre and total bar weight instantly. Useful for order estimating, bending schedule checks, and material accounting without touching a spreadsheet.
Compliance Checklist
Compliance paperwork is dull. Missing it is expensive. Run through the checklist (certificates, traceability, documentation) and know your deliveries are actually covered.
Material Yield Planner
Plan parts from sheets or slabs while accounting for cutting loss (kerf) to reduce scrap and estimate usable leftover material.
Manufacturing Cost Calculator
Estimate manufacturing costs (material, processing, and labour) so your quotes don’t leave money on the table.
Want More Than Calculators?
These tools are free because we want you to see what GoSmarter can do. When you’re ready for real-time inventory, automated cert reading, or AI-powered cut planning, we have paid products that go much further. For AI-powered compliance and traceability, GoSmarter starts at £180/month with 50% off your first month.
The free tools work best as a starting point. Use the scrap rate calculator to understand your current waste levels, then try Cutting Plans to see how much you could save with a better cut plan. Use the business case calculator to build the numbers for sign-off, then get started on a free trial.
