Frequently asked questions
Why convert through meters internally?
Using a single canonical base unit keeps conversions consistent and avoids maintaining separate formulas for every unit pair.
Can this be used for construction and classroom math?
Yes. The included units cover many common use cases from everyday measuring to technical problems.
Does rounding change the underlying conversion?
No. Rounding only affects display. The internal conversion still uses the precise unit factor.
