Frequently Asked Questions

Are my kitchen measurements or room dimensions sent to any server?
No. All calculations run entirely locally within your browser using client-side JavaScript. No details about your home or recipes are transmitted.
Can I use these tools offline while working in the garden or garage?
Yes. Once the page is loaded, the calculation engines do not require an active internet connection to execute, making them ideal for offline use in any room or outdoor space.
How precise are the culinary conversion calculators?
They use standard international food measurement standards. However, since densities can vary (e.g. flour vs water), weight-to-volume estimations are based on standard average densities.
