  The conversion factor from feet to miles is 0.00018939393939394, which means that 1 foot is equal to 0.00018939393939394 miles:
  
  1 ft = 0.00018939393939394 mi
  
  To convert 2.1 feet into miles we have to multiply 2.1 by the conversion factor in order to get the length amount from feet to miles. We can also form a simple proportion to calculate the result:
  
  1 ft → 0.00018939393939394 mi
  
  2.1 ft → L(mi)
  
  Solve the above proportion to obtain the length L in miles:
  
  L(mi) = 2.1 ft × 0.00018939393939394 mi
  
  L(mi) = 0.00039772727272727 mi
  
  The final result is:
  
  2.1 ft → 0.00039772727272727 mi
  
  We conclude that 2.1 feet is equivalent to 0.00039772727272727 miles:
