The phrase "at a precision" is correct and usable in written English.
It can be used when discussing the level of accuracy or detail in measurements, calculations, or processes.
Example: "The experiment was conducted at a precision of 0.01 grams to ensure accurate results."
Alternatives: "with a precision of" or "to a precision of".
