About Engineerly

Engineerly is a small collection of electrical power calculators for engineers, technicians and students. It covers the everyday questions of power distribution: line current, kVA and kW, generator sizing and fuel, cable voltage drop, transformer loading, power factor correction, battery runtime and off-grid solar.

Why it exists

Many online calculators give a single number with no indication of how it was reached. For engineering work that is not good enough. You need to see the formula, know what was assumed, and be able to check it. Every Engineerly result is shown with its working, its assumptions and its limits, and the logic is tested against hand calculations as described in the methodology.

Principles

• Standard formulas, cited to the standards and texts that cover them.
• Defaults are visible and editable, and labelled as typical values rather than facts about your equipment.
• Everything runs in your browser. Nothing you enter is uploaded or stored on a server.
• An honest statement of what a simplified calculation cannot tell you. See the disclaimer.
