 On-scale temperature is _unique_ among quantities in this respect; for all other quantities, zero means the same whatever the unit of measurement. For example (using **bold** to indicate a numerical data value), **0** `kilogram` is the same mass as **0** `pound`, but **0** `degC` is not the same temperature as **0** `degF` (= **-17.8** `degC`), because these two temperature **`units`** implicitly refer to measurement scales which have different origins.
 
 On the other hand, when the temperature value is a _temperature difference_, which compares two on-scale temperatures with the same origin, the value of that origin is irrelevant as it cancels out when taking the difference.
-Therefore to change the **`units`** of a temperature difference requires only multiplication by a scale factor, without the addition of an offset.
+Therefore to convert the **`units`** of a temperature difference requires only multiplication by a scale factor, without the addition of an offset.
 
 The **`units`** attribute does not distinguish between on-scale temperatures and temperature differences.
 This ambiguity also affects units of temperature raised to some power e.g. `K^2` or multiplied by other units e.g. `W m-2 K-1`, `degF/foot` or `degC m s-1`.
 A **`standard_name`** (<<standard-name>>) or **`standard_name`** modifier (<<standard-name-modifiers>>) may clarify the intention, but they are optional.
 Some statistical operations described by the **`cell_methods`** attribute (<<cell-methods>>; <<appendix-cell-methods>>) imply that temperature must be interpreted as temperature difference, but this attribute is optional too.
 
-In order to change the **`units`** correctly, it is essential to know whether a temperature is on-scale or a difference.
+In order to convert the **`units`** correctly, it is essential to know whether a temperature is on-scale or a difference.
 Therefore this standard strongly recommends that any variable whose **`units`** involve a temperature unit should also have a **`units_metadata`** attribute to make the distinction.
 This attribute must have one of the following three values: `temperature: on_scale`, `temperature: difference`, `temperature: unknown`.
 The **`units_metadata`** attribute, **`standard_name`** modifier (<<standard-name-modifiers>>) and **`cell_methods`** attribute (<<appendix-cell-methods>>) must be consistent if present.
