53.6 hectometers (hm)
536 meters (m)
536,000 millimeters (mm)
53,600 centimeters (cm)

Answer : The incorrect option is, 53.6 hectometers (hm)

Explanation :

(1) The conversion used from kilometers to hectometers is:

1 km = 10 hm

Converting the given value, we get:

The value in hectometers is 5.36 hm

(2) The conversion used from kilometers to meters is:

1 km = 1000 m

Converting the given value, we get:

The value in meters is 536 m

(3) The conversion used from kilometers to millimeters is:

1 km = 1000000 mm

Converting the given value, we get:

The value in millimeters is 536000 mm

(4) The conversion used from kilometers to centimeters is:

1 km = 100000 cm

Converting the given value, we get:

The value in centimeters is 53600 cm

Hence, the incorrect answer is, 53.6 hectometers (hm)
