In English, "of" is generally used for physical quantities, for example:
a height of 30 meters [高さ30メートル]
a width of 15mm
an area of 10 square kilometers
a volume of 300 milliliters
a weight of 10 kilograms [重さ10キログラム]
a diameter of one billion light years
a current of 3 amperes [電流3アンペア]
a current of 3A
In the world there are 14 mountains with a height of more than 8,000 meters
The largest is the Canada goose, which reaches a weight of 14 pounds and a wingspan of 6 feet
a height of 30 meters → h = 30m
a height of over 30 meters → h > 30m
a height of more than 30 meters → h > 30m
a height of less than 30 meters → h < 30m
I hope this answers your question!
