FAQ

Are your constants exact?

Yes. Based on the exact meter definition.

How do you round?

We display up to 4 decimals for mid-range numbers and more for small values.

Practical Use Cases

Step-by-Step Derivation

If a base relation gives 1 mi in terms of km, multiply your km value by that constant to get mi. Alternatively, if 1 km equals a fixed amount of mi, multiply by that instead.

  1. Identify the base relation on this page (exact when available).
  2. Multiply your Kilometers (km) by that constant.
  3. Round the Miles (mi) for readability if needed.

Inverse Check (Quick Validity Test)

Take your mi result and convert it back to km. If you land near your original input (within rounding), the calculation is consistent.
