If you divide that, you get 1.2 feet per stud, or 0.8333... studs per foot.
So, say you have an 85 foot long ship. Simply multiply by 0.833 and you have a 71 (70.83) stud, in length, ship.
I'm doing a replica of the HMS beagle which is 90.3 feet long, calculated out to 75 studs and 24.5 feet wide, calculated out to 20 studs (just thought I might share an application of these conversions)
For those of you that don't use feet, in measurement, one foot = 0.3048 meters, so minifigs would be 1.8288 meters tall, meaning the ratio would be 1.8288:5 or for every five studs in lego, it is about 1.8 meters in real life.
If you divide that, you get 0.36576 meters per stud, or 2.7340332458442694663167104111986 studs per meter (just to be exact)
So, say you have a 45 meter long ship. Simply multiply by 2.734 and you have a 123 (123.03) stud, in length, ship.
Also here is a "stud converter site" That would probably help a lot too... (BTW calculations from this site are not exactly the same as mine, FYI)
If you feel like "setting" the height of your minifig, say, you think minifigs are 5 feet tall (like blueandwhite thinks) just convert to inches and divide by 1.625 (thats how many inches tall minifigs are if you include nub on top) to find the scale. Then, simply convert the length of the real life object to inches, multiply by the ratio in fraction form (1/x) to find the length of the model in inches, and since one stud is 0.3125 inches, divied the number you came up with by 0.3125 to find th length in studs...
For example, say you want figs to be 5'10", convert to inches (70), divide by 1.625, just add 1:x (or 1/x) and you have your ratio (1:43.076923 or 1/43.076923)
Then, if you wanted to make a real life object using YOUR OWN minifig scale, simply convert its length (say 24 feet) to inches (288 inches), then multiply that by the ratio in fraction form (288x(1/43.076923) and you have it length in minifig scale, in inches (6.6857142976530612458090379389447 inches), divide by 0.3125, and you have the length in studs... (21, really 21.394285752489795986588921404621 rounded)
*anyone need that in metric?
