A kilometre is a measure of length or distance in 1-dimensional space while a feddan is a measure of area in 2-dimensional space. The two measure different things and, according to basic principles of dimensional analysis, any attempt at conversion from one to the other is fundamentally flawed.
1 feddan = 4,200.883 meter square
I assume you mean fathom, There are 1.8288m in a fathom. if you meant feddan, this is a unit of area, not length
one thousand
One million what?
100 kilometers = 100000 meters
1 feddan = 4,200.883 meter square
I assume you mean fathom, There are 1.8288m in a fathom. if you meant feddan, this is a unit of area, not length
1.61 kilometers = one mile
1.609 kilometers
There are 1,000,000,000 kilometers in a terameter.
really? 1,000,000
One
one thousand
One million what?
21 kilometers = 13.05 miles
One mile is approximately 1.61 kilometers.
There are 1.609344 kilometers in one mile. Therefore to convert kilometers to miles, value in kilometers has to be divided by amount of kilometers in one mile: 6370 kilometers = [kilometers] / 1.609344 = 6370 / 1.609344 = 3958.13 miles
