Convert the unit pairs commonly needed in lighting projects — lux↔footcandle, metres↔feet, Kelvin↔mired, watts↔BTU/hour — bidirectionally, all in one place. You can also enter an IP rating code (e.g. IP65) to see what it means for solid-particle and liquid ingress protection per IEC 60529 — a quick reference when selecting outdoor or damp-location fixtures.
