Turn a Measured Firewood Stack Into Seasons of Supply

A woodpile is a volume; a winter is a consumption. Measure the stack's three dimensions once and the arithmetic tells you how many seasons it stands between you and an empty shed.

1 · Stack code | length m | height m | depth m

HYPOTHESIS / PROTOTYPE — checkout unavailable. Calculation is local. A draft is saved automatically in this browser profile when storage is available; Reset to sample clears it. Optional Pro history stores only five summaries and has its own deletion control. State links encode your inputs and can remain in browser history, clipboard or recipients’ records; share only non-sensitive rows. Optional external AI formatting leaves this device. The required site analytics beacon reports page activity; shared URLs contain encoded inputs. Do not treat an encoded URL as private. The calculator has no input-collection endpoint.

Data note: The stack-volume chart processes Stack code | length m | height m | depth m locally. Starter/sample selection and Run compute in this tab; no input is sent by the calculator. A local draft may be saved; explicit state-link sharing or optional external AI formatting can disclose inputs. Use non-sensitive labels.

Perspective: Before: the woodpile was reassurance measured by eye. After: it is cubic metres against a stated seasonal consumption, with seasons and remainder named.

Volume arithmetic on reader-supplied dimensions and consumption only, not a heating, safety or purchasing guarantee. Check seasoning, appliance instructions and local burning rules with the relevant responsible sources before relying on any wood supply.

Optional filing controls are a local prototype.

Before using the stack-volume chart

Measure the stack itself — the rectangular envelope it actually occupies — not the wall or shed behind it, and use one unit convention (metres here) throughout. Air gaps inside the stack are included by design: consumption figures you compare against should be stacked-volume figures too, so the convention cancels. If your consumption history is quoted in loose volume, weight or 'loads', convert it to stacked cubic metres under one stated assumption before entry. The seasons figure is a ratio, not a forecast: an actual season's draw depends on weather, stove use and household habits that no geometry can know. Stacking safety, seasoning time and legal burning rules sit outside the chart entirely.

Optional AI formatting, never the calculation

Manual entry completes this stack-volume chart for free without signup. If available to you, the free AI Studio interface linked in the sources may format fictional or non-sensitive notes; external access may require an account. No API key or AI call is built into this tool. Free-tier content may be used to improve products. Review each cell and transcribe it to the labeled row schema; do not paste the JSON object into the row box.

Format only these fictional or non-sensitive notes for a stack-volume chart. Return strict JSON shaped as {"rows": [{"label": "string", "cells": ["string", "string", "string"]}], "setting": "string"}. The columns are Stack code | length m | height m | depth m; the setting is Season consumption (m³ of stacked wood). Keep all supplied strings and quantities exactly; do not calculate, infer missing entries, invent dates or add advice. If any required value is missing, return an empty rows array and ask me for it separately. I will verify every cell against my source and manually transcribe rows using vertical bars before running the local calculator.

An AI response is not executed, fetched or trusted as a result. Missing values remain questions; the strict local parser checks the rows you actually enter.
