Many thanks everyone...
Super helpful for the badge review, and interesting to hear how we all have go-to sources to work this stuff out... APMM Forum rocks!!
Jenny, Years ago, as a UK graduate working in California, I remember working half a fast as I tried to work in decimals of an inch! Millimetres rock too! |

Will,
I build site models quite often for work. I have a quick cheat sheet that I use at work. Seems like no one customer likes the same scale. I uploaded to my Google Drive feel free to use it. It is not pretty but it gets the job done.
It is dynamic in the sense that I can change the scale and the Real Distance Bar on the far right will update. If I need to convert from Real Feet to Scale Inches, I use the conversion on the bottom. And vice versa.
If you want a airplane model scale like 1:48, change inches to 12 and feet to 48.
Hope this helps your Boy Scout Troop.

Will --
Working for an architecture/planning firm in the US, we do a fair number of models looking at large areas. Often, for ease and speed, we use an Imperial Engineering scale. 1"=40', 1"=50', 1"=60', or even 1"=100' or 1"=200' work well (choose depending on the size of the area you want to cover and the desired end size of your model), and are easy to track while working using a triangular Engineer's scale. |

Imperial scales show inches to the left and ft to the right, ie:
1/4"=1'
In converting from metric, start by converting the right hand side to ft, ie divide by 12.
1:1000 metric would be 1"=84'
1:2000 would be 1"=166'
Fun fact: Three countries on our planet use imperial as their standard measuring system; Liberia, Myanmar and the USA.

US president Jimmy Carter tried to get the US to learn/use the metric system in the 1970s. Unfortunately he failed.
I am literally twice as fast and twice as accurate as my modelmaking colleagues when I do wirecut foam, since I use millimeters and not ridiculous measurements like 5/32nds or 7/64ths. |

1/8th inch to 10 feet would be 1:960 and 1/16th inch to 10 feet would be 1:1920. I suppose those might be close enough considering a lot of US small stock is sold in imperial sizes. I would hope the BSA would just have them convert it all to metric and skip the shenanigans, though. |

WoodlandScenics.com offers a free scale conversion app. Use the "Custom" setting to get either 1:1000 or 1:2000 or any scale you maybe working with. |

Hi Will,
1/48 is 1/4" to the foot. 1:1000 equals 0.001" per inch or .012" per foot. 1:2000 would be 0.0005" per inch. That's some small stuff. |

If 1:50 is equivalent to about ¼ in to 1ft, what would be the equivalent of 1:1000 and 1:2000?
I’m writing about master planning models as part of the scouts badge review we’ve been asked to help with. |
