Free Earthing Tools

Earthing Tools & Calculators

Seven free, instant earthing tools — soil resistivity, strip weight, pipe weight, earth resistance, conductor sizing, pit count and a full BOQ builder. Every tool shows the formula and the source of its numbers, so you can check our working rather than take it on trust.

Soil Resistivity Calculator → Convert a Wenner four-pin field reading and pin spacing into apparent soil resistivity in ohm-metres, with the IS 3043 formula and test guidance. GI & Copper Strip Weight Calculator → Weight per metre and total kilograms for any GI or copper earthing flat strip — standard or custom size — with a verified weight chart. GI Earthing Pipe Weight Calculator → IS 1239 (Part 1) nominal weight for GI earthing pipe — by nominal bore, class, length and quantity, plus a custom OD × wall estimator. Earth Resistance Calculator → Estimate pipe-earthing resistance (IS 3043 / Dwight formula) from soil resistivity, electrode size and number of pits — with IS 3043 target guidance. Earthing Conductor Size Calculator → Fault current to minimum cross-section by the adiabatic method (IS 3043 / IEC 60364-5-54), with the smallest GI or copper strip that meets it. Earth Pit Count Calculator → Estimate how many 40 NB × 3 m earth pits meet a target resistance, with the single-electrode result, combining factor and spacing assumption. Earthing BOQ Builder → Turn a resistance target or pit count into a full materials list — pits, pipes, salt, charcoal, strip and accessories — as one WhatsApp enquiry. Ask Our Team on WhatsApp

Please read. These figures are general projections, not a design. They are estimates based on published formulae, standard weight data and assumed uniform soil conditions — real sites vary, and the numbers here may not be 100% accurate. They are offered as a working aid only. Global Electric Company accepts no liability for decisions taken on the basis of these results: always have them checked and signed off by your site engineer, electrical consultant or a qualified professional, and confirm earth resistance by measurement on site before commissioning. Where these tools and IS 3043 disagree, IS 3043 wins.
