LEGO Converter

ABOUT

I made this utility to help you easily convert between feet, meters, and LEGO units if you're trying to recreate something in LEGO Fortnite Odyssey with the same scale and proportions as in real life.

Lego Fortnite Odyssey has a scale, in meters. But I wanted to know the sizes of the individual pieces because I want to build scale models of real buildings, aircraft, boats, and landmarks. I laid 100 16x16 floors pieces end to end and measured the distance. It was exactly 256 meters.

• that means 1600 LEGO units = 256 meters
• and so 1 LEGO unit = 16 centimeters (0.16 meters)
• then 1 meter = 6.25 LEGO units (6.25 * 0.16m = 1m)

For a simple chart, see my original Reddit post

As always, let me know if you find bugs or have ideas for improvements! Msg me on Reddit, Discord, YouTube, or Twitch.

Just a couple of tweaks:

• When you click the "nearest unit of 2" checkbox, it recalculates the LEGO value. You can go back and forth now without having the enter the same number over and over.
• Added a little spacing between METERS and LEGO. You'll only notice this on desktop.

v1.2, October 11, 2025

I got some great feedback from my new post on Reddit, especially from Tukaro. So I just made the following updates:

• Did a general cleanup of some code, changed input fields to type="number" (easier to use on phones) and a few other little details. The page is now fully validated HTML5. Yay!
• Tweaked the CSS to be more responsive. On desktop, the input fields lay out horizontally now, but if you're on a tablet or phone, everything will wrap as needed. If you're on a mobile device the font sizes should automatically increase as well.
• When you click or tap a field, any existing number is automatically selected so you can just type a new number without having to select and delete first. I just find this faster on my phone.
• An optional "nearest unit of 2" checkbox under LEGO gives you results in even numbers. Since most LEGO pieces are 2, 4, 6, 8 etc., this should make it easier to choose your pieces. For example, 30.6 LEGO units would be rounded to 30, but 31.3 would be rounded to 32.

v1.1, October 10, 2025

Originally, I only had a FEET field, but I've seen many floorplans with feet and inches so I added an INCHES field. You can still enter decimal feet values, like 16.25 feet (this is 16ft 3in) or you can enter feet and inches. BUT don't use both at the same time or your results won't be accurate. For example, if you enter 16.25 in FEET and 3 in INCHES, this will end up being 16 feet 6 inches!

When you convert from LEGO or Meters BACK TO feet, I'm rounding to the NEAREST INCH because I didn't want fractional inches. This really shouldn't make a difference in your builds anyway but I just wanted to point it out. I thought about making the FEET field accept whole numbers only, but I wanted this utility to be super simple and if you'd rather enter decimal feet instead of inches, you can.

v1.0, October 8, 2025

Just finished coding the first version of my LEGO Converter. I'm testing out on Twitch right now! I added this page as a browser source in OBS then just made the background transparent. I'm building a trailer park in Lego Fortnite Odyssey and I downloaded a bunch of floorplans for different sized mobile home trailers. Having my utility on the screen makes it SO MUCH easier to get everything to scale.
