How many hectometer are there in 9 mm?

Answer 1

1 hectometer = 100 m

1000 mm = 1 m

⇒ 1000 mm x 100 = 1 hm

⇒ 100000 mm = 1 hm

⇒ 9 mm = 9 mm ÷ 100000 hm

= 0.00009 hm

Answer 2

There are 0.000009 hectometers in 9 millimeters. To convert millimeters to hectometers, you divide by 10,000 (1 hectometer = 10,000 millimeters).
