FAQ
Can I just type the conversion in words?
Yes — the box at the top understands plain phrases like "5 mi to km", "72f to c", "3 cups in ml" and even heights like "6'2\" to cm". If it can't parse something, the classic dropdowns below always work.
Which units are supported?
Length (miles, km, feet, inches, cm, yards), Weight (kg, g, pounds, ounces, stone), Volume (liters, ml, gallons, cups, tbsp, tsp, fl oz), Temperature (Celsius, Fahrenheit, Kelvin), Area (m², km², ft², yd², acres, hectares) and Speed (km/h, mph, m/s, knots, ft/s).
Is it accurate for cooking?
Yes — US cups, tablespoons and teaspoons are included, which is handy for converting recipes.
Does it work offline?
Conversion runs in your browser, so once the page is loaded it works without sending any data.
Can I control the number of decimals?
Yes — choose Auto or a fixed 0/2/4/6 decimal places, see the exact conversion rate, and copy the result with one click.
Are there shortcuts for common conversions?
Yes — one-tap chips for the most-used pairs (miles↔km, cm↔inches, kg↔lb, cups↔ml, °C↔°F and more) set both units instantly.
Can I save my own frequent conversions?
Yes — hit the ☆ star next to the unit selectors to pin the current pair. Pinned pairs appear as ★ chips at the top and are stored on this device only.
Does it understand mixed units like 5 lb 8 oz?
Yes — type phrases like "5 lb 8 oz to kg", "11 st 4 lb to kg" or "6'2" to cm" and the parser combines the parts before converting.
