About these everyday calculators

The practical tools: converting between units, counting working days, sizing a concrete pour, subnetting a network, checking fuel economy. Small questions that are quick to answer wrongly in your head.

Conversion factors and physical constants are the standard published values. Where a result depends on a material property, a local code or a regional convention, that value is exposed as an input so you can match it to your situation rather than accepting a US or metric default.
