How to Convert Chi (Chinese foot) to Kilometres (chi to km)
Length conversions come up when reading overseas furniture specs, cycling the Round Island Route in kilometres while a foreign app shows miles, or checking marine distances in the Singapore Strait in nautical miles. This guide shows how to convert chi (chinese foot) into kilometres by hand, with examples and a quick-reference table.
The conversion
To convert chi (chinese foot) to kilometres, multiply the value by 0.0003333333. To go the other way, divide by the same number (or multiply by 3,000). Because the factor is tiny, scientific notation keeps the numbers manageable.
Kilometres = chi (chinese foot) × 0.0003333333
Worked examples
- 3 chi = 0.001 km
- 12.5 chi = 0.004167 km
- 75 chi = 0.025 km

Mistakes to avoid
Dropping the units
A bare number without a unit is easy to misread later. Always write the unit with the result.
Rounding the factor too early
Using 3 instead of 3.28 for feet per metre introduces an error of almost 9% before you have started.
Forgetting squared and cubed units
Area and volume factors are the length factor squared or cubed, so 1 m² is about 10.76 sq ft, not 3.28.
Background
A conversion table is handy for common values, but a calculator is faster and avoids interpolation errors for anything in between.
Writing the units next to every number while you work is the simplest way to avoid mistakes. If the units do not cancel to leave the one you want, the calculation is set up wrongly.
For everyday use, three or four significant figures are usually enough. Engineering, science and trade documents may need more, and rounding should happen only at the end of a calculation.
