# Weight mode default

> Set which weight entry mode opens by default in the POS for all weight-based products.

When a vendor taps a weight-based product in the POS, a keypad appears with a toggle to choose how to enter the weight. The **Weight mode default** setting controls which mode that toggle opens in.

## Changing the default

1. In the PopUp admin, go to **Settings**
2. Find the **Weight mode default** section
3. Choose your preferred default:
   * **% w/w** — the keypad accepts a single decimal number (e.g. `0.73` for 0.73 lbs). Use this if your scale displays a decimal reading.
   * **Weight** — the keypad accepts a compound reading where digits before the decimal are the larger unit and digits after are the smaller unit directly (e.g. `2.5` = 2 lb 5 oz, or `1.350` = 1 kg 350 g). Use this if your scale displays lb/oz or kg/g.
4. Tap **Save**

The new default takes effect immediately the next time a product is opened in the POS.

## Per-product memory

The POS remembers the last mode used for each product on that device. If a vendor switches a product from the default to a different mode, it will open in that mode next time — on that device only. Switching to a different POS device resets to the store default.

## Which mode to choose

| Your scale displays         | Recommended default |
| --------------------------- | ------------------- |
| `0.73 lb` or `0.350 kg`     | % w/w               |
| `2 lb 5 oz` or `1 kg 350 g` | Weight              |

If you're unsure, leave it as **% w/w** — it works the same as before this feature was added, and vendors can always toggle per-product.
