Engineering tools for people who build

Chinese ⇄ English translation tuned for construction and BIM, quantity calculators that run on deterministic formulas, and a searchable engineering glossary — with metric and imperial units and step-by-step working you can check.

Engineering Translation

Chinese ⇄ English for tenders, specs, method statements and site correspondence — tuned to construction and BIM terminology, with the glossary terms it matched shown back to you.

Tenders · specs · technical clauses → open the app

Engineering Calculators

Concrete volume, rebar weight, mix design, earthwork, asphalt, masonry, steel weight and unit conversion. Deterministic formulas, not AI guesses.

Concrete · rebar · earthwork · asphalt · steel → 23 calculators

Unit Converter

Metric ⇄ imperial across length, area, volume, mass, force, pressure, moment and density — the everyday headache when one project mixes two unit systems.

Metric ⇄ imperial → convert now

Engineering Glossary

Chinese ⇄ English terminology across structures, concrete, geotechnical, roads, MEP, plant, contracts, HSE, surveying and BIM. Search in either language.

Document Translator

Upload a Word, Excel, PowerPoint, PDF or text file and get a Chinese ⇄ English translation laid out paragraph by paragraph — same glossary, same wording across the whole document.

DOCX · XLSX · PPTX · PDF → translate

Why this is built differently

Deterministic, checkable

Every calculator exposes INPUT → ASSUMPTIONS → CALCULATION → RESULT. No AI is used to compute numbers, so results can be audited line by line.

Metric + imperial

Plenty of projects mix SI with US/UK units. Switch systems on any page; conversion factors follow international definitions.

Built for working engineers

For engineers, quantity surveyors and site teams who need translation, unit conversion and quantity checks in the same place — without juggling three unrelated tools.
