Why we built these tools

Traders, purchase teams and engineers search for these numbers every day. Most online calculators are full of ads, slow on mobile or limited to one material. Our tools are:

  • Made for phones — big inputs, fast results
  • Instant — no sign-up
  • Offline-friendly — work once opened, even with weak signal on site
  • Free

From calculator to quotation

Calculators are perfect for quick checks. When you need to quote many items with weights, GST or export currency, QuoteMitra does the same calculations automatically across your whole quotation and creates a professional PDF.

Example: quoting a pipe order in two minutes

A buyer asks for 120 metres of 4" SCH 40 carbon steel pipe:

  1. Open the pipe schedule chart: 4" SCH 40 = 114.3 mm OD, 6.02 mm wall.
  2. Use the pipe weight calculator: about 16.07 kg/m, so 120 m ≈ 1.93 tonnes.
  3. Use the steel price calculator with your rate per kg to get the price per metre and total with GST.

In a couple of minutes you have weights and prices you can trust — ready to send or to enter in your quotation.

Tips for accurate results

  • Use the exact OD from the standard, not the nominal size.
  • Choose the correct material — stainless is about 1–2% heavier than carbon steel.
  • Remember that coatings, sockets and tolerances change actual weight.
  • Round only at the final step.

Who uses these tools

  • Traders and stockists — quick weights and prices during buyer calls
  • Purchase engineers — checking supplier quotations
  • Site supervisors — estimating quantities and loads
  • Students and new staff — learning standard dimensions
  • Exporters — planning container payloads by weight

Share the tools page with your team so everyone uses the same reliable numbers.
