I'd like to know where you're from, because "dunam" is a term used rarely in America. Most don't even know what it is! But since you're asking, here's the extended version of the answer:
A dunam in modern times is 1,000 square meters; this is equal to 10, 763.91 square feet.
An acre is 43, 560.174 square feet.
Since an acre is much larger than a dunam, I'm wandering why you're not asking, "How many dunams are in an acre?"
So I'm going to answer both question to eliminate any confusion.
There is less than one-fourth of an acre in a dunam (0.2471043 to be exact).
And there are over four dunams in one acre (4.0468727 to be exact).
A dunam is usually now 1000 square meters, though in the past it has varied in different countries. So 1 dunam = 0.247 acre.
1 Donem, or Dunam, is a unit of land area from the Ottoman Empire which is still used in some countries, though not consistently defined. In Iraq, a dunam is 2500 square meters, (1/4 hectare) while in Jordan, Lebanon, and Turkey a dunam is 1000 square meters (1/10 hectare).
feet and a measure of lengh while acres are a measure of area. I'll assume you mean square feet. 94 acres are 37.6 hectares. each hectare is 10 dunams, each dunam has 1000 square meters and each square meter has 27 square feet...
a dunam= 1000m2 a hectare= 10 dunam
One thousand (1,000).
19.305 square miles.
I'll answer approximately. A square kilometer is exactly one thousand dunams, and a dunam is roughly one-quarter acre. So five acres would be roughly one-fiftieth of a square kilometer.
.97 acres.
Exactly 0.459 acres.
