Frequently asked questions
How many square meters in an alqueire?
The alqueire paulista, used here, is 24,200 m² — the same as 2.42 hectares. Brazil has other alqueires (the mineiro is 48,400 m²); this tool uses the paulista, the most common in land listings.
How do I convert Fahrenheit to Celsius?
Pick the temperature category, Fahrenheit in "From" and Celsius in "To". The formula behind it is (°F − 32) × 5/9 — but you don't need to memorize it: type the value and the answer appears.
Is the gallon US or imperial?
US, 3.785 liters — the one in recipes, paint cans and car specs. The imperial gallon (4.546 L) is a different measure and is not included.
What cup size do you use?
The standard recipe cup: 240 mL. The tablespoon is 15 mL. Those are cookbook values — the cup in your kitchen may vary a bit.
Why does the result have so many decimal places?
We show up to 8 significant digits so the conversion works both for estimating (1 mile ≈ 1.6 km) and for precision work. Round it however you need.
Do I need internet to convert?
Only to open the page. The math happens in your browser, on your device — no value is ever sent to any server.
