### How to change ft to Nm?

To convert a foot measurement to a nanometer measurement, multiply the length by the conversion ratio. One foot is equal to 304,800,000 nanometers, so use this simple formula to convert: 1 ft = 304,800,000 nm nanometers = feet × 304,800,000 The length in nanometers is equal to the feet multiplied by 304,800,000. For example, here's how to convert 5 feet to nanometers using the formula above. 5' = (5 × 304,800,000) = 1,524,000,000 nm

### What is the radius of a 3/4 acre circle (in feet)

Oh wow, lots of math going on here... There are 4840 square yards in an acre and 9 square feet in a square yard (4840 x 9 = 43,560). An acre is an old timers measurement used in agriculture... it was 4 poles wide and 40 poles long. A pole is equivalent to sixteen and a half feet. So back then, an acre was a piece of farming land 660 feet long (220 yards or one eighth of a mile) and 66 feet wide (22 yards or one eightieth of a mile). Acre is a measure of area, which would be square feet. Feet are a measure of distance. The best you could do is something like this: An acre is 43, 560 square feet. Draw/imagine a square or a rectangle that would cover that much area. If it is a square, it would be (approximately) 208.7 feet on each side. Its perimeter (the distance around it if you walk an imaginary fence around you acre-sized plot) would be 834.8 feet. Trying to to figure out an acre of 'Circle' - hmmmmm??? Radius = 1/2 of Diameter sorry, just can't wrap my head around this to come up with the correct equation. maybe we can get lucky with some other brainiac taking what I did provide and come up with a solution for you? Square - It would be 208.7 feet across if you walk across it, and the same if you walk the other way across it.
