Best practice

When using "keep constant at" in scientific writing, specify the units of measurement to provide clarity and avoid ambiguity. For example, "keep the temperature constant at 25°C" is clearer than "keep the temperature constant at 25".

Common error

Avoid switching between different units of measurement when describing the constant value. If you start with Celsius, continue using Celsius throughout the section, unless there's a clear reason to convert.
