Which units should I enter?
Bed length uses centimeters. Bed width uses centimeters. Row spacing uses centimeters. Plant spacing uses centimeters. Convert values to these units before calculating.
Which formula does it use?
Rows = floor(width/row spacing); positions = rows × floor(length/plant spacing).
What does the included example show?
Bed length: 300 centimeters; Bed width: 120 centimeters; Row spacing: 30 centimeters; Plant spacing: 20 centimeters. Result: Rows = 4; Positions per row = 15; Total positions = 60.
Can I compare different settings?
Yes. Save a scenario, change the inputs and save another result. Up to five scenarios are compared in this tab; they disappear when you reload or leave.
Can I export the calculation?
Copy the JSON report or download JSON and CSV with inputs, result labels and numeric values. Processing uses local JavaScript; no calculation request is sent to our server. Displayed values use up to 10 significant digits; exports retain JavaScript numeric precision.
