How do you convert distance to meters?

Kilometer and Meter

  1. A kilometer is a unit of distance in International System of units (SI).
  2. A meter is also unit of distance as well as length.
  3. To convert value of length in kilometer to meter, we have to multiply the given value by 1000.
  4. 1 km = 1000 meters.
  5. 5 km = 5 x 1000 = 5000 meters.

How many meters in 1 degree?

So, for latitude the number of degrees from the pole to the equator is 90∘, and the number of meters is 10 million (or 10,000 kilometers). That means 1∘ of latitude is 10,000/90=111 kilometers, and 0.001∘=0.111 kilometers or 111 meters, essentially an American football field plus both endzones.
 

How many meters is 0.0001 degrees latitude?

11.1 m



0.0001 = 11.1 m.

How many km is 0.25 degree?

one degree near the equator is equivalent to around 110 km, and moving to south or north the longitude degree value decreases, but the latitude degree value almost remains the same. So 0.25 latitude degree near the equator is equivalent to about 27-28 km.
