Conversion formula

The conversion factor from knots to kilometers per hour is 1.8519999999969, which means that 1 knot is equal to 1.8519999999969 kilometers per hour:

1 kt = 1.8519999999969 km/h

To convert 231 knots into kilometers per hour we have to multiply 231 by the conversion factor in order to get the velocity amount from knots to kilometers per hour. We can also form a simple proportion to calculate the result:

1 kt → 1.8519999999969 km/h

231 kt → V_(km/h)

Solve the above proportion to obtain the velocity V in kilometers per hour:

V_(km/h) = 231 kt × 1.8519999999969 km/h

V_(km/h) = 427.81199999929 km/h

The final result is:

231 kt → 427.81199999929 km/h

We conclude that 231 knots is equivalent to 427.81199999929 kilometers per hour:

231 knots = 427.81199999929 kilometers per hour

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 kilometer per hour is equal to 0.0023374753396391 × 231 knots.

Another way is saying that 231 knots is equal to 1 ÷ 0.0023374753396391 kilometers per hour.

Approximate result

For practical purposes we can round our final result to an approximate numerical value. We can say that two hundred thirty-one knots is approximately four hundred twenty-seven point eight one two kilometers per hour:

231 kt ≅ 427.812 km/h

An alternative is also that one kilometer per hour is approximately zero point zero zero two times two hundred thirty-one knots.
