I think it is reasonable to assume you mean acres however this question can not be answered because it doesn't make sense. You can not compare an acre with a kilometre because they are not measurements of the same thing. A kilometre is a one dimensional measurement, so for example we can measure a line and say it is 1km long. An acre, however, is a two dimensional measurement and can not be used to measure something, such as a line, which is only one dimensional. You can not equate one with the other. Instead you can compare an acre with square kilometres as this too is a two dimensional measurement. An acre is about equal to about 0.004 square kilometres (accurate to 3 decimal places only) and you could fit about 247 acres in a square kilometre.
1 km = 1000 m 1 km has 1000m.
Answer: 1 mi. = 1.60934 km
1 meter = 0.001 km (1/1000 km)
1 km.
1 km
1/100,000 km
Answer: 1 km = 0.621371 miles
1 mm= 1/1000 km
1 foot = 0.0003048 km
There are 1,000 meters in 1 Km
10,000 decimeters in 1 km
1 km = 0.62 mi
