Simple Physics Toolkit Plugin: Unit Conversion, Volume Caculator and Mass Distribution

A simple plugin to help with creating physically accurate games and models.

Unit Conversion

  • Length: Studs ↔ Meters/Feet
  • Mass: RMU ↔ Kilograms/Pounds
  • Force: Rowtons ↔ Newtons/Pound-force
  • Torque: Rowton-studs ↔ Newton-meters/Pound-feet
  • Switch between metric and imperial units
  • Customizable scale (default 0.28m per stud)

Volume Calculator

  • Calculate dimensions based on target mass and density
  • Lock specific dimensions to adjust proportionally
  • Real-time updates as you modify values
  • Apply dimensions directly to selected parts

Model Mass Editor
Update 12/8/24: Replaced this with a distribution editor, details here

Perfect for:

  • Vehicle creation
  • Physics-based games
  • Mechanical assemblies
  • Realistic construction
  • Any project requiring precise physical properties

The plugin is free here

Im willing to take any suggestions for new tools.

What the fiddlesticks is a kilometer???

But seriously, this plugin is really cool for people who are wondering what a stud is in feet, or to make physics in your game more accurate. Nice plugin.

Made it out of anger because i was getting tired of doing it with a calculator lol. I’m surprised there wasn’t a existing one already.

bumping this since i decided to turn this plugin into a general toolkit for physics related purposes. Added a volume caculator and a mass distributor for models/assemblies.

has the plugin been deleted?

Heck yeah. Can’t wait for getting into using physics! This is perfect for my future projects. Thank u bro (Ur plugin is not showing pls update the link)

It was working on my side so i thought it was still good, i changed it now.

Here’s the new link: https://create.roblox.com/store/asset/132588822577638/Physics-Toolkit

still not accessible :frowning:

Thats odd, the link works perfectly fine on my side even after i logged out.

weird, it seems to work now, maybe it just had issues loading for me

Can you send a photo of the moderation note , when the first was deleted?

Its fixed, what most likely happened was that i changed the name of the plugin without updating the link.

NEW UPDATE:

I have replaced the model mass widget with a more powerful model distributor editor.

selecting a model will create a copy of the model into this viewport, color coding it based on its contribution to the total mass (blue to green to red).

It has the option like the previous widget of setting the total mass of the model, but with 3 distribution options instead of one:

  • Uniform Contribution - Makes all the parts contribute equally to the total mass.
  • Uniform Density - Makes all the parts the same density
  • Proportional - Scales the mass in those parts to the total mass while keeping their contribution ratios.

You can move around the viewport and select parts of the model that are valid (parts with massless set to false). You can set the target mass and density of these selected parts to a specified value for more control.

You can also lock the mass of selected parts such that they don’t change during distribution calculations. the editor will used the unlocked parts to achieve the target mass of the model. They will show in the editor as forcefield parts.

Finally after your changes you can apply them to the original model, or not and move on to another model.

As always, i’m open to feedback on the UI and suggestions for new features.
