§ 02 / ABOUT
Four categories, ~30 units.
This converter handles the four categories that cover 95% of everyday conversion: length, weight, temperature, and volume. Each unit has an internal reference (SI where possible), and conversions are applied in two steps — input to reference, reference to output — so any pair of units within a category can convert losslessly.
// HOW EACH CATEGORY WORKS
- Length — reference is the meter. Linear conversion (multiply by a constant).
- Weight — reference is the gram. Linear conversion.
- Temperature — reference is Celsius. Affine conversion (offset + slope). °F to °C isn't just a multiply; it's
(F − 32) × 5/9. Kelvin adds 273.15. - Volume — reference is the liter. Linear, but watch out for US vs imperial gallons (3.785 L vs 4.546 L).
// FOR COOKING
General volume conversion is fine for liquids. For dry ingredients like flour or sugar, volume ↔ weight depends on the ingredient — a cup of flour is 120g, a cup of sugar is 200g. Use Cups → Grams for ingredient-aware density tables.

§ 02 / FAQ
Questions. Answered.
Which unit systems are supported?+
Metric (SI) and US customary for length, weight, and volume. Temperature supports Celsius, Fahrenheit, and Kelvin. Imperial-specific variants (UK gallon, stone) can be added on request.
Are the conversion factors exact?+
Yes, where exact values exist by international definition. 1 inch = 0.0254 m exactly. 1 pound = 0.45359237 kg exactly. 1 gallon (US) = 3.785411784 L exactly. Results are displayed to 6 significant digits with locale-aware separators.
How do I share a conversion?+
The URL updates as you type: /convert/length/100-cm-to-in means 100 cm to inches. Paste that URL anywhere and the recipient gets the same calculation pre-loaded. The SHARE button also gives you copy link, native share, X, Reddit, email, and plaintext options.
How is temperature different?+
Temperature isn't a linear multiplier like length or weight. Converting 0°C to °F isn't 0 — it's 32. The engine uses proper affine formulas: (°F − 32) × 5/9 = °C, °C + 273.15 = K.
Is there a cups-to-grams converter?+
Cups to grams is not a unit conversion — it's an ingredient-dependent recipe conversion (1 cup of flour weighs differently than 1 cup of sugar). We may add that as a separate tool. This converter does cups to milliliters / liters / fluid ounces, which are true volume conversions.
Does my data leave my browser?+
No. Everything is computed client-side. The URL syncs locally — if you don't paste it anywhere, no one sees your query.
