# Input Units vs. Report (Display) Units

## This article explains the difference between Input and Report (Display) Units when reporting data.

### **Input Units**

**Input Units** represent the **final value after any formula is applied** and **must match the LODs, LOQs, and Limits** if applicable. If units don’t match, **comparisons will be incorrect.**

### **Report Units**

**Report Units** are the units of the results the lab wants displayed on the COA.

For labs testing Cannabinoids, these are controlled by the **Primary Display Unit** and **Secondary Report Unit** fields. A **Tertiary Report Unit** field can be added on request. The default behavior is that the **Primary Display Unit** also controls the Cannabinoid statboxes **(Total THC, Total CBD, Total Cannabinoids).**

For all other assays, the report unit is controlled by the **Primary Display Unit** field. 

### **Example: Cannabinoids**

- **Raw value:** ug/ml
- **LODs and LOQs:** mg/g 

Since the **LODs and LOQs** are in **mg/g,** the final value formula provided by the lab calculates to **mg/g.** *This way, its final value, LODs, and LOQs all match the same unit: mg/g.*

The **Input Units** is therefore **mg/g**:

The lab then uses the **Primary Display Unit** and **Secondary Report Unit** fields to control which units the results are reported on the COA (e.g., **%, mg/g, mg/ml, mg/unit, mg/serving, mg/container, ppm**, etc.)
