Decimal In · Fraction Out

Type any measurement into A or B — decimals, mixed fractions like 5 3/8, or full feet-and-inches like 5 6 3/8 (auto-reads as 5' 6 3/8"). Switch between inches, metric, volume, and more with the BIG button. Pick an operation, hit equals — the result comes back as a clean fraction you can read right off a tape.

No pop-ups. No pop-unders. No eight banner ads stacked above the fold. Just the math.
