# Translations with OpenTelemetry 0.7.0 format

CloudWatch performs some transformations to put CloudWatch data into OpenTelemetry format.

**Translating namespace, metric name, and dimensions**

These attributes are key-value pairs encoded in the mapping.

One pair contains the namespace of the metric

One pair contains the name of the metric

For each dimension, CloudWatch stores the following pair:

`metricDatum.Dimensions[i].`

`Name`

, metricDatum.Dimensions[i].`Value`

**Translating Average, Sum, SampleCount, Min and Max**

The Summary datapoint enables CloudWatch to export all of these statistics using one datapoint.

`startTimeUnixNano`

contains the CloudWatch`startTime`

`timeUnixNano`

contains the CloudWatch`endTime`

`sum`

contains the Sum statistic.`count`

contains the SampleCount statistic.`quantile_values`

contains two`valueAtQuantile.value`

objects:`valueAtQuantile.quantile = 0.0`

with`valueAtQuantile.value =`

`Min value`

`valueAtQuantile.quantile = 0.99`

with`valueAtQuantile.value =`

`p99 value`

`valueAtQuantile.quantile = 0.999`

with`valueAtQuantile.value =`

`p99.9 value`

`valueAtQuantile.quantile = 1.0`

with`valueAtQuantile.value =`

`Max value`

Resources that consume the metric stream can calculate the Average statistic as
**Sum/SampleCount**.

**Translating units**

CloudWatch units are mapped to the case-sensitive variant of the Unified code for
Units of Measure, as shown in the following table.

Units that are combined with a slash are mapped by applying the OpenTelemetry conversion of both the units. For example, Bytes/Second is mapped to By/s.
