The volume in cubic feet.

Bagged potting soil, compost and mulch in North America are sold by the cubic foot, and concrete mixers and wheelbarrows are rated by drum or tray volume in cubic feet. For a box-shaped space, multiply length × width × height, all in feet.

Volume

56.63 L

High confidence

1 ft = 0.3048 m exactly, so 1 cubic foot = 0.3048³ m³ = 28.316846592 L exactly. Round only the final figure, and buy bagged material by the whole bag count the volume needs.

  • NIST SP 811, Appendix B — 1 ft³ = 0.02831685 m³
  • International yard and pound agreement, 1959 — the foot is exactly 0.3048 m, so 1 ft³ = 0.3048³ m³ = 28.316846592 L exactly
  • BIPM, The International System of Units (SI Brochure), 9th edition — the litre is 1 dm³ = 0.001 m³

Plans and products from North America describe volume in cubic feet — bagged potting soil and bark, concrete mixer drums, wheelbarrow trays, refrigerator capacities, compressor tanks — while European catalogues, specifications and bag labels use litres. This converter sits between the two whenever a plan from one market meets a product from the other. The factor is exact, so the errors that matter happen around it: a mixer's drum size is not the batch it can mix, which is smaller and usually stated separately, and a volume of loose bagged material shrinks once it is placed and firmed. Convert the measured volume, then allow for both before counting bags or loads.

Frequently asked questions

How many litres is a 2 cubic foot bag?
About 56.6 litres. The same products sold in Europe come in round litre sizes, so a 2 cu ft bag sits between the 50 and 60 litre bags rather than matching either — compare the volumes, not the bag counts.
Is a cubic foot of bagged soil a cubic foot in the bed?
Not quite. Bagged growing media is loose and settles once it is spread, watered and firmed, so a bed measured in cubic feet usually takes more bagged volume than its dimensions say. Convert the measured volume, then round the bag count up.
Is the conversion exact?
Yes. The foot has been exactly 0.3048 metres since 1959, and a litre is exactly a cubic decimetre, so one cubic foot is exactly 28.316846592 litres. Keep the full figure through the working and round only the answer.
Preliminary estimate, not certified engineering. This tool produces an indicative quantity calculation for planning purposes only — it is not a certified structural analysis, a guaranteed material takeoff, or a substitute for building department approval. Always verify measurements on-site and have a licensed contractor or structural engineer review any load-bearing, code-sensitive, or safety-critical work before purchasing materials or starting construction.
