Raised bed soil calculator

The same pure function powers the free browser tool and the paid API, so a phone estimate matches the line item a script posts later. Zero or negative length, width or height is rejected with a clear invalid_input message instead of a silent nonsense volume.

How raised-bed soil volume is computed from length, width and height

Conversion uses fixed international-foot constants so identical inputs always produce identical JSON: zero point three zero four eight metres per foot, zero point zero two five four metres per inch, one centimetre equals zero point zero one metre, and one cubic yard equals twenty-seven cubic feet. Intermediate fields length_ft, width_ft, height_ft, length_m, width_m and height_m are returned so you can audit the unit path against a supplier quote. Length, width and height must all be strictly positive: zero or negative values are rejected with invalid_input because a non-positive side makes volume non-physical or zero.

What you send and what you get back

Send three required finite numbers: length and width for the plan footprint of the bed interior, and height for the intended soil fill level or wall height. Optionally send unit as ft, in, m or cm; omitted unit defaults to feet. Classic checks include eight by four by one foot: thirty-two cubic feet, about one point one nine cubic yards, and about zero point nine zero six cubic metres. Missing required fields, non-numeric strings, NaN and Infinity fail with invalid_input and are not charged. When length, width or height is zero or negative the request fails with a message that the dimension must be positive, so clients can correct the measurement before retrying instead of receiving a zero or negative volume. On success the response echoes cleaned inputs and the resolved unit, each side in both feet and metres, volume_native as the product in the caller’s unit cubed, volume_ft3 for cubic feet, volume_yd3 for cubic yards, volume_m3 for cubic metres, volume_l for litres, a unit_note reminder of the defaults and formulas, and a short formula string for documentation. Another useful check is two metres by one metre by zero point three metres with metric unit: volume is zero point six cubic metres and six hundred litres. Pricing for successful API calls is the published base of $0.002 per item; validation failures do not consume prepaid balance.

Where raised bed soil calculators show up in real work

Homeowners building a first vegetable bed from a kit or scrap lumber need a trustworthy cubic-yard figure before calling a landscape supplier, especially when bulk delivery has a minimum load and bags are expensive once opened. Landscape crews and garden centres embed a raised-bed volume helper next to bulk soil and compost SKUs so shoppers convert kit sizes into the unit the product is sold in. If you later need bag counts from a specific bag yield, waste percent as a separate field, circular beds, lawn topsoil area-and-depth coverage, or mulch-only depth tables, treat those as separate search intents and landings rather than overloading this raised bed length-width-height soil calculator page. Community garden coordinators and school garden projects size multiple frames of different lengths and wall heights; a single deterministic endpoint that reports cubic yards, cubic metres and litres reduces spreadsheet drift between the volunteer who measures and the person who orders. Property managers renovating courtyard planters feed each length-width-height triple through the API and attach volumes to purchase orders so overstock stays intentional rather than guessed. Because this capability is a pure parse engine, API pricing is the published base of $0.002 per successful item and failed validation does not consume balance.
