## What is Scale Ratio?

Scale a measurement to a larger or smaller measurement, which is useful for architecture, modelling, and other projects.

This app can be used to easily convert any distance in any scale to any other distance in any other scale.
Simply enter the distance and scale to convert and the result will be displayed instantly.

You need for example to create a mock up of a building at the scale 1:500.
Enter the ground distances in the calculator, set the scale ratio to 1:500 and you'll get the mock up distance.

## Key features

- Convert distances between any scales
- Supports architecture and modeling projects
- Instant calculation of scaled distances
- User-friendly input for distance and scale

### 4/5 — Good, but could be great!

*2022-09-02*

Love the concept, sufficient customisability to assist with a broad range of tasks, my only (nit-picky) complaint is that even though you can change which unit you are using for the input part of the calculation, the output is automatically assigned a unit

### 4/5 — So far so good, but

*2021-01-21*

I am happy so far, but would make a couple tweaks. I would prefer to have the metric and imperial options combined. Sometimes I only have measurements in imperial but I want the output to be in metric. It would be nice to have this option. Basically, I would like to choose the output/resultant unit of measurement. 

Where you change the scale size isn’t apparent that you can change it. The quick start tutorial does indicate that you can and it works well, just thought that visually it may be better to indicate somehow.

It isn’t a complicated app, and there are a lot of nice little details. It has a nice interface and would use it much more often if I could choose the output length type.
