# Item Units of Measure _(Realtime-enabled)_

`GET` _(Table: Item Unit of Measure)_

```
eOne/core/v1.0/itemUnitsOfMeasure
```

Read-only feed of an item's units of measure: pack/conversion factors plus per-UoM dimensions and weight for shipping and cartonization. Exposed standalone and as the expandable child of [Items](https://eonesolutions.github.io/eone-bc-integration/core-items.md) via `?$expand=itemUnitsOfMeasure`.

Each row is one UoM line on an item. `qtyPerUnitOfMeasure` is the conversion factor back to the item's base unit, and `length`/`width`/`height`/`cubage`/`weight` describe the physical pack at that UoM.

## Resolver: itemId

The feed exposes the parent item by both its business key (`itemNo`) and its Business Central record GUID (`itemId`). `itemId` is not stored on the UoM record. It is resolved per row by looking up the [Item](https://eonesolutions.github.io/eone-bc-integration/core-items.md) from `itemNo`, so you can join straight to the Items endpoint without a second call.

> **Caution:** This feed carries **no `integrationId`**. Item units of measure are not [Integration Id](https://eonesolutions.github.io/eone-bc-integration/integration-id.md)-stamped. Correlate rows by `itemNo` + `code`, or pull them through the Items expand.

> **Caution:** The endpoint is **read-only** (no create, update, delete, or bound actions). Maintain item units of measure in Business Central.

| API | BC field | Notes |
| --- | --- | --- |
| `id` | SystemId | BC record GUID; the OData key. _(ro)_ |
| `bcCompanyId` | bcCompanyId | The company this row belongs to - the same GUID that appears in the request URL. Present on every endpoint so a store pooling several companies can keep them apart without relying on which URL it called. _(ro)_ |
| `bcCompanyName` | bcCompanyName | The name of the company this row belongs to. _(ro)_ |
| `itemNo` | Item No. | Parent item business key. _(ro)_ |
| `itemId` | itemId | Parent item GUID, resolved from `itemNo` via the Item record. _(ro)_ |
| `code` | Code | Unit-of-measure code. _(ro)_ |
| `qtyPerUnitOfMeasure` | Qty. per Unit of Measure | Conversion factor to the item's base unit. _(ro)_ |
| `qtyRoundingPrecision` | Qty. Rounding Precision | _(ro)_ |
| `length` | Length | _(ro)_ |
