# Units
**Adding Units**
-----------------------------------------------------
**Step 1: Access Units**
-------------------------------------------------------------
- Go to **Products → Units**.
**Step 2: Add a Basic Unit**
-----------------------------------------------------------------
1. Enter the **Unit Name** (e.g., Meter).
2. Enter a **Short Name** (e.g., Mtr.).
3. Choose whether to **Allow Decimals**.
- Enabling decimals allows buying and selling in fractional quantities.
**Step 3: Add Multiple Units (Optional)**
------------------------------------------------------------------------------
- Use this when purchasing and selling in different units.
- **Example**: Purchase in dozens, sell in pieces.
- **Example**: Purchase in boxes, sell in pieces.
### **Steps**
1. Add the **lower unit** first (e.g., Pieces).
2. Add the **higher unit**:
- Check **“Add as multiple of another unit.”**
- Enter the **conversion ratio**.
3. When adding/editing products, select the desired unit from the dropdown.
- Purchase and sales prices adjust automatically.
4. **Note:** Only the lower unit is used to store transactions. Changing conversions later will adjust existing purchase/sales quantities accordingly.
**Step 4: Enable and Select Relevant Sub-Units (Optional)**
------------------------------------------------------------------------------------------------
- Useful if only some sub-units apply to a product.
- **Example**: Sell oranges only in dozens or pieces.
### **Steps**
1. Enable feature: **Business Settings → Products → Enable relevant sub-units**.
2. When adding a product, select the main unit and choose the applicable sub-units.
3. Purchases and sales can now be performed in these selected sub-units.
