How: mile: Exactly 5280 feet = 1609.344 m (statute mile).
kilometer: 1 km = 1000 m.
Shortcut in your head: multiply by 1.6. That gives about 1.6 against the exact 1.609: very close (off by 0.58%).

Define a unit once (“1 lap = 400 meters”) and it joins the lists and the text box, saved on this device. It must measure something that scales in a straight line, so not temperature or fuel economy.

Conversions you settle on are remembered here (up to 40), only on this device.
How it works, honestly: each unit is defined from an exact statement (for example 1 inch = 25.4 mm, 1 pound = 0.45359237 kg, 1 US gallon = 231 cubic inches), and the tests check every pair of units both ways. Cooking weights are typical values, not lab measurements. Months and years use their long-run averages. There are no live exchange rates here: you enter your own, and each is saved with the date you set it.
Private by design: this runs on your device and nothing you enter is uploaded. What it remembers stays in this browser. See and manage your data.
