The measurement in feet.
Enter inches as a decimal part — 20 ft 6 in is 20.5 ft. Dividing inches by twelve gives the decimal.
Length
6.096 m
1 foot = 0.3048 m exactly, following from the defined inch. Timber and sheet goods come on different modular grids in each system — a converted length rarely matches stock.

Estimated cost — your price
This site holds no price list for this material — local prices vary too much to publish honestly. Enter your supplier's price and the result is costed with it.
Computed in your browser — nothing you enter is uploaded. Presented in US customary units and US trade terminology. Where a formula follows a published standard, that standard and its edition are cited beside it on this page; where none governs, the page says so. Local amendments override model codes — verify against the code in force where you build.

Most jobs need more than one number. Add the calculators you need next and they open right here, underneath this one — your figures stay on screen and nothing is lost to a page change.
Structural schedules, drainage runs and setting-out dimensions all cross this boundary when a project spans markets. The factor is exact and follows directly from the defined inch. Where it becomes practical rather than arithmetic is stock length: imperial markets sell timber in eight, ten and twelve foot lengths, metric markets in 2.4, 3.0 and 3.6 metre lengths, and those two grids do not line up. A converted requirement therefore lands between available sizes far more often than not, and the take-off has to be done against whatever grid the supplier actually stocks rather than against the converted figure. On large sites, be aware too that the retired US survey foot differs marginally from the international foot.
