Kilomile: Unit Converter

Kilomile is a unit converter that works the way you would ask a person. Type "5 ft 7 in to cm", "3 cups flour in grams" or "1 kanal in marla" and the answer appears as you type, with the exact definition it comes from. Metric and imperial, side by side.

EXACT, NOT ROUNDED
Rounded conversion factors let small errors creep in. Kilomile calculates with exact fractions taken from each unit's published definition (1 inch = 2.54 cm exactly) and rounds only when it shows the result, to the precision you choose. Every conversion shows its definition and its source, such as NIST or the BIPM SI Brochure.

TYPE IT OR TAP IT
• Smart search understands amounts, mixed units and plain words: "5 ft 7 in to cm", "100 f to c", "2 stone 5 lb in kg", "60 mph in km/h"
• Spelling slips and plurals are fine: "fahrenheit", "farenheit", "feet", "foot"
• Or open any category and use the large keypad; swap units with one tap
• See a value in every unit of a category at once
• Pin the pairs you use most; your recent conversions are one tap away

LAND AND LOCAL UNITS, DONE RIGHT
Kilomile knows the units people actually use, with the variant for your region:
• Pakistan and India: marla, kanal, gaj (square yard), bigha, biswa, katha, guntha, cent, ground, tola, maund, seer
• Nepal: ropani, aana, paisa, daam, bigha, kattha, dhur
• Egypt: feddan, qirat and sahm, as defined in Egyptian law
• Middle East: dunam
• UK and US: stones and pounds, feet and inches, US and imperial gallons
A marla in Lahore is not the same as everywhere else, so Kilomile shows which one it uses and lets you compare variants side by side.
