There is now answer to that but is your question supposed to be 'How many milimeters are in one foot?' Look at what I wrote below:
1ft=12 in
12in=24cm
1cm=10mm
This might help you but you still have to do math but i will give you a hint why don't you try this, this should help you, think however many feet you are using by how many cm's are in the foot or feet then try to figure out how many mm's are in those cm's. Here look below:
2cm= 1in
1ft=12in
1in=20 mm
This should help you now. Good Luck!

Answer: 1 km = 3,280.839 feet.1 kilometer=3,280.8399 feet
34 feet, there are 3 feet in 1 yard.
1 metre = 3.28084 feet
1 meter = 3.2808399 feet
1 mile is 5,280 feet.
1 millimeter is 0.0032808 feet.
1 decameter = 32.808399 feet
There is 5280 feet in 1 mile.
1 fathom = 6 feet
12 inches = 1 foot 3 feet = 1 yard 5280 feet = 1 mile
