[Feature]: General base number instead of fixed 5-feet for all distance calculations

[angelod1as]

Describe the Problem

I'm playing DnD 5e but I'm not in a country that measures with imperial system. All our material is translated, so instead of saying my character speed is 30 feet, we say it's 9 meters.

I thought about changing the grid — instead of distance per cell being 5 it would be 1.5 — every square is 1.5 square meters.

But changing this number breaks every other cell-calculated measurement, e.g. lighting. When I choose candle, for instance, it lights 5 "units" — if my grid was in feet, it would be 1 square. When I changed it, it lighted almost 4 squares.

The generic lighting works the same, as the numbers are 5, 15, etc, and they light 5 units (like the torch). Huge lights.

So, changing the grid distance per cell makes every other numbered map tool useless to me. I went back to 5 distance per cell and now I have to calculate everything from meters to feet.

The Solution you'd like

WDYT about adding a general number that all calculations take into account would solve it? A variable that interferes with all distance calculations?

E.g.: let's suppose the variable unit has 5 as default, so candlelight range is unit, everburning is unit * 4, lamp is unit * 3 and so forth.

This way, when I change my unit in the settings to 1.5, the lights magically also change! Now candlelight is unit (1.5), everburning is unit * 4 (6), lamp is unit * 3 (4.5) and so on.

Alternatives that you've considered.

There could be a simple "metric" or "imperial" dropdown in the settings, but I think this would low customisability in favour of description.

Instead of using a default unit, the software could calculate lights or similar by square (or hex, or grid unit). That way one light lights N squares — independent of the distance measurement used.

Additional Context

In my country, every DnD official books (in my native language) have these imperial-to-metric changes, so calculating the movement lenght or using the ruler also relies on this "default unit".
