Question

Convert the length 6 ch 21 km to feet.

Answer 1

Here, ch stands for chain

Where,

1 ft = 66 chains  

1ft = 1 km×3280.84  

So, let’s convert 6 ch 21 km to feet

First convert

6 ch to ft= 6× 66 = 396 ft  

Then convert 21 km to ft

21 km to ft = 21× 3280.84  

     = 68897.64 ft  

6 ch 21 km= 396 ft + 68897.64 ft  

      = 69293.64 ft

Hence 6 ch 21 km to 69293.64 ft.
