About this site

Zuqva is a small site with two jobs: help you estimate your daily calorie needs, and help you convert recipe measurements without guessing.

It was built as a side project, not a company. There is no account, no subscription, no newsletter trap and no data collection. The calculators run entirely in your browser — the numbers you type never leave your device, because there is no server to send them to.

The TDEE calculator uses the Mifflin-St Jeor equation, a standard, widely published formula. The kitchen converter uses a published density table, shown in full on the converter page, with results labelled approximate because real ingredients vary.

What this site is not: it is not medical advice, it is not a diet plan, and it does not replace a doctor, dietitian or experienced cook. If a number here disagrees with your own scale or your doctor, trust the scale and the doctor.

Questions or corrections? See the contact page. If you spot a wrong density or a formula error, that is exactly the kind of message worth sending.
