The two big display preferences in Gold Silver Ledger — what currency to show money in, and what unit to show weights in — live on the same tab in Settings and follow the same underlying rule: the app stores everything in one canonical form (USD for money, troy ounces for weight) and converts to your chosen display preference at the moment a page is rendered.
Switching either one is a few clicks, no migration, no historical data rewritten.
This article is the short version. Each preference has a deeper article of its own if you want the long form.
Where to find them
Both preferences live on the Profile tab of your Settings page.
From the left nav, click Settings.
The page opens on the Profile tab by default. If you've navigated away, click it.
The Display Currency card sits in the top-right of the Profile tab.
The Weight Unit card sits below it on the left.
That's the whole map.
Changing your display currency
The Display Currency card has one control — a Currency dropdown — and a banner reading "Changing your display currency does not affect stored transaction data or historical records — only how values are shown in the app."
Pick the currency you want from the dropdown.
Click Save changes at the bottom-right of the page.
That's it. Every page in the app re-renders in the new currency on the next load.
You can pick from any of 15 supported currencies: USD, EUR, GBP, CAD, AUD, CHF, JPY, NZD, HKD, SGD, MXN, ZAR, SEK, NOK, and DKK. If your home currency isn't on the list, leave the app in USD and convert manually for any official paperwork — the list is being expanded over time.
For the longer version of how conversion actually works (where rates come from, how often they refresh, what happens to historical values when you switch), see Setting your display currency in the Getting Started collection.
Changing your weight unit
The Weight Unit card has one control — a Weight unit dropdown — and a matching banner reading "Changing your weight unit does not affect stored transaction data or historical records — only how weights are shown in the app."
Pick the unit you want from the dropdown.
Click Save changes at the bottom-right of the page.
You can choose from three options:
Troy ounces (oz): The default, and the unit the precious-metals world uses globally. One troy ounce is about 31.10 grams.
Grams (g): More familiar to anyone outside the US, and the right choice if you primarily think in grams when you buy.
Kilograms (kg): Mainly useful if you stack at scale — kilo bars, large silver bars, that sort of thing.
Every weight shown in the app — on Holdings, Dashboard cards, transaction details, Analytics — re-renders in your chosen unit on the next load.
For more detail, including how the conversion is applied and worked examples, see Setting your weight unit in the Getting Started collection.
What changing either preference doesn't do
This is the rule that ties both cards together, and it's worth understanding once.
Money is stored in USD. Every purchase price, sale price, cost basis figure, and premium-over-spot lives in the database as a US dollar amount. Picking GBP as your display currency means the app converts that USD figure to GBP each time it draws the page; it doesn't rewrite the underlying record.
Weight is stored as fine metal content in troy ounces. Every coin and bar carries a stored weight that already represents the pure metal it contains. Picking grams or kilograms means the app converts that troy-ounce figure for display; the stored number doesn't move.
A practical consequence: you can switch back and forth between currencies, or between ounces and grams, as often as you like. Each switch is just a different conversion of the same underlying numbers. There's no migration step, no "lock in" date, no separate "before" and "after" history.
This is also why a value you recorded last year can look slightly different in your display currency from one day to the next. The dollars haven't moved; the FX rate has.
Save changes is grouped at the page level
One small UI note: the Save changes button at the bottom-right of the Settings page saves both cards together. If you change the currency and the weight unit in the same visit, one click commits both.
If you change one, change your mind, and navigate away before saving, neither change takes effect — only saved changes are applied.
