What are you working out?
Choose a calculation. Every tool includes its units, formula and a worked example.
Rectangular Bed Area
A measured bed area anchors soil, mulch and planting estimates.
Open calculator ↗Circular Bed Area
A circular bed's footprint depends on the square of its diameter.
Open calculator ↗Triangular Bed Area
Triangular corners can be included in a garden plan by measuring a base and its perpendicular height.
Open calculator ↗Raised Bed Soil Volume
A raised bed behaves like a shallow box for a first soil-volume estimate.
Open calculator ↗Soil Bag Count
Bag volume translates the planned fill into a whole-bag purchase.
Open calculator ↗Cylindrical Pot Volume
A straight-sided round container can be estimated as a cylinder.
Open calculator ↗Tapered Pot Volume
A linearly tapered round pot resembles a conical frustum.
Open calculator ↗Rectangular Planter Volume
A rectangular planter volume helps estimate how much growing medium to prepare.
Open calculator ↗Mulch Volume
Mulch demand follows the area to cover and the chosen layer depth.
Open calculator ↗Mulch Bag Count
Whole-bag purchasing rounds the volume requirement upward.
Open calculator ↗Compost Top-Dressing Volume
A thin top-dressing can be planned separately from the full bed fill.
Open calculator ↗Compost Share of Mix
A volume-based mix ratio assigns part of a batch to compost.
Open calculator ↗Soil Mix Remainder
Subtracting known components preserves the target batch volume in a simple additive recipe.
Open calculator ↗Grid Plant Count
A square grid estimates planting positions by fitting equal spacing cells into a rectangular bed.
Open calculator ↗Rectangular Spacing Count
Different in-row and between-row spacing allows a row-based planting estimate.
Open calculator ↗Plants per Row
A spacing-cell convention allocates one plant per complete segment along the row.
Open calculator ↗Row Count
The bed width divided into row-spacing cells gives a consistent row count.
Open calculator ↗Row Length for Plant Count
Working backward from plant count estimates row length including two half-spacing edge margins.
Open calculator ↗Seeds for Expected Germination
A germination rate converts the desired average seedling count into a sowing estimate.
Open calculator ↗Expected Seedlings
The expected seedling count combines seed number with a germination fraction.
Open calculator ↗Seed Packet Count
Packet counts turn a seed plan into whole purchase units.
Open calculator ↗Tray Count
A cell tray plan assigns one target seedling to each available cell.
Open calculator ↗Tray Growing Medium
Cell volume and tray count determine the total medium to prepare.
Open calculator ↗Succession Sowing Batches
Counting a sowing at day zero and at each full interval gives the number of scheduled batches.
Open calculator ↗Water Volume from Depth
One millimetre spread over one square metre equals one litre, linking irrigation depth and volume.
Open calculator ↗Watering Depth from Volume
An applied volume can be expressed as an equivalent uniform depth.
Open calculator ↗Hose Runtime
A bucket-tested flow rate translates a water-volume target into hose runtime.
Open calculator ↗Bucket-Test Flow Rate
Timing a known bucket volume provides a practical flow measurement.
Open calculator ↗Drip Zone Flow
Emitter count and rated flow estimate the demand of a drip zone.
Open calculator ↗Drip Irrigation Runtime
Dividing a volume target by zone flow gives a first runtime estimate.
Open calculator ↗Rain Capture Volume
Catchment area and rainfall depth estimate potential collection after an efficiency allowance.
Open calculator ↗Rain Tank Fill Share
Comparing collected volume to tank capacity shows how much storage it represents.
Open calculator ↗Tank Supply Duration
A steady daily demand converts stored water into a simple duration estimate.
Open calculator ↗Weekly Watering Total
Summing equal watering sessions makes a weekly consumption record easier to compare.
Open calculator ↗Measured Irrigation Efficiency
Measured retained water compared with applied water describes a defined efficiency estimate.
Open calculator ↗Bed Edging Length
A rectangular bed perimeter gives the total edging run.
Open calculator ↗Circular Edging Length
A circular border's length follows its circumference.
Open calculator ↗Garden Path Gravel
A straight uniform path uses rectangular-layer geometry.
Open calculator ↗Landscape Fabric Roll Length
An area-based roll estimate includes a user-entered allowance for overlaps and cuts.
Open calculator ↗Plant Label Count
A labeling plan keeps repeated rows and spare labels visible in one count.
Open calculator ↗Support Twine Length
Repeated support lines can be totalled before adding an allowance for ties.
Open calculator ↗Harvest per Plant
An average per-plant harvest helps compare your own recorded batches.
Open calculator ↗Harvest per Area
Area-normalized harvest makes differently sized plots easier to compare.
Open calculator ↗Seedling Survival Rate
A survival rate records the share of transplanted plants still present at a chosen checkpoint.
Open calculator ↗Water per Harvest Mass
Irrigation divided by harvested mass offers a simple record-based comparison.
Open calculator ↗Growing Degree Day Simple
A simple growing-degree-day value accumulates warmth above a chosen base temperature.
Open calculator ↗Average Daily Harvest
A daily average summarizes production across a recorded interval.
Open calculator ↗Garden Area in Square Feet
Area conversion helps compare garden plans that use different unit systems.
Open calculator ↗Litres to US Gallons
A US liquid gallon equals 3.785411784 litres.
Open calculator ↗Cubic Yards to Litres
Bulk landscape materials sold in cubic yards can be compared with bag volumes in litres.
