Metric Republic’s 96 Engineering Calculators
A free browser-based library of construction and engineering calculators covering materials, geometry, MEP, energy, water, estimating, and structural design.
Field notes
The site organizes its tools by both workflow and discipline, spanning concrete quantities, steel weights, thermal performance, airflow, voltage drop, runoff, and editable cost allowances. Its more advanced studios are presented as connected calculation sequences: the electrical workflow moves from load power to design current and cable comparison, while the structural workflow follows reactions through columns and footings. Metric and imperial inputs are supported, and the homepage cautions that engineering tools are for transparent preliminary calculations rather than complete professional checks.
