Calculator inputs

Calculations run in your browser. This version does not send bed measurements, crop choices, quantities, or results to an application server. There are no user accounts or cloud-saved plans.

Moving between tools

When you choose an action that carries measurements to another tool, the site uses session storage in the current browser tab. This holds the transferred dimensions or settings until used or until the browser ends that session. It is not a cross-device backup. If storage is blocked, the site tells you to re-enter the values.

Clear transferred tool data

Reset returns a tool to its default example. Closing a page loses unsaved in-memory edits. Printed results and downloaded CSV files are under your control on your device.

Cookies, analytics, and ads

The homepage loads Google AdSense code. Google and its advertising partners may use cookies to serve ads based on visits to this and other websites. When personalised advertising is enabled, advertising cookies can be used to tailor ads. You can manage Google personalised ads in My Ad Center. Read how Google uses information from sites that use its services and how AdSense uses cookies. The calculators use tab session storage for transfers as described above; fonts and first-party site assets are served locally.

Hosting and external links

The hosting service may process normal request information such as IP address, browser details, requested page, and time for delivery and security logs. This page does not claim a specific server-log retention period. External source links take you to other organisations with their own privacy practices.
