    How do I convert tenths & hundreth to inches
    Example: finished floor elevation were taken at -0.02 how do I convert to inches.
    0.01=
    0.02=
    0.03=

    also
    0.10=
    0.20=

    or is there a chart already set up

    Thanks in advance

    Try this convertor.

    http://www.onlineconversion.com/auto_convert.pl

    You just type what you want to convert. For example, type in:
    Convert 10 inches to centimeters
    and it will return:
    10 inches = 25.4 centimeters

    I never seem to remember it, but I think that is the one you need for your conversions.

    The easiest way to think of decimals is 0.10 is like 1/10
    0.01 is like 1/100 hope this was of some help.

      If we're dealing with tenths and hundredths of feet, just multiply by twelve.

        Hi, are you talking about somewhere in the US? - Some other places use meters above or below a datum point. 0.01 might be 10mm, 0.1 might be 100mm.

          Thanks for the help, Leopold you were correct multiply by 12
          Hopefully this will help others.

          0.01=.12=1/8 inch
          0.02=.24=1/4
          0.03=.36=3/8
          0.04=.48=1/2
          0.05=.60=5/8
          0.06=.72=3/4
          0.07=.84=13/16
          0.08=.96=15/16
          0.09=1.08=1 1/16


          Thanks

            tenths of a foot to inches

            .1 = 1-3/16"
            .2 = 2-3/8"
            .3 = 3-5/8"
            .4 = 4-13/16"
            .5 = 6"
            .6 = 7-3/16"
            .7 = 8-3/8"
            .8 = 9-5/8"
            .9 = 10-13/16"

              An inch is .083 of a foot. Or Eighty three thousandths. So you would do 6" times .083 which is .498. Pretty close to half a foot. Or to convert 5 tenths to inches you would take .5 divided by .083 which is 6.0240963855421686746987951807229. If you are talking about international survey foot.

                Well, your 0.083 has too little precision and your 6.0240963855421686746987951807229 has way too much. Unless the 0.083 were known to be exact, more than two significant figures in the result is meaningless.

                12" = 1' exactly, so 1" = 1/12 ft, or 0.08333..... a continuing decimal (to infinity). 0.5 ft = 6 inches, exactly.

                  I tried to post a link to a chart but the forum wont let me, so I hope this helps. In FF, elevations are considered above sea level. The feet are on left of decimal, inches on the right of decimal thus an elevation of 600.63 = 600' -7 5/8" above sea level. Now this elevation or any elevation can be called your benchmark and called 00.0 , using 0.02 above this mark would be called +0.02 and below this mark would be -0.02 , or +1/4" or -1/4"
                  For shooting grades a close rule of thumb is 1/8 of an inch = 0.01 so 0.02 = 1/4 and there's 8 of them in an inch. Now 12 inches in a foot must be divided into 10 parts so if 12"= 1'.00 then 6"= 0.50 or 1/2 a foot (2x6=12) and 3"= .25 or 1/4 of a foot (3x4=12) It's not rocket science it's construction if it varies slightly by an 8th or so, oh well, close enough. Of course, I'm thinking concrete and gradeing

                    I have a water line that is 14" in diameter. The lenght is 20,731 ft.
                    How do i figure out how many gallons are in the pipe?

                      You have to work in consistent units, either feet or inches. Since the gallon is defined in cubic inches, I'll convert the length to inches
                      20731 ft x 12"/ft = 248 772 in

                      Volume of a cylinder (pi/4)*D*d*L =
                      0.785 x 14 x 14 x 248772 = 38 295 474 in³

                      A gallon is 231 in³, so 165 781 gallons

                        there are 7.17 gallons per foot for 14" pipe.
                        7.17 X 20,731 = 148,641.3

                          Sorry but there are 7.99678 gallons in a cylinder with an inside diameter of 14" and a length of 12"

                          Volume per foot: PI * 7in2 * 12 in / 231 in3/gal = 7.99678 gal/ft

                          7.99678 gal/ft * 20,731 ft = 165,781 gallons in line. John's answer is correct.

                            Yes, if 14" is a bona fide inside diameter. If it is a "name" like 2x4, the poster's value could be right, but only if the real diameter is 13.256"
