Reply to comment by critterfluffy in How would one calculate the gravity of a planet? by LoreCriticizer

So what does your statement even mean then? Your answer is only good to however many decimal places your least precise measurement/constant is. But what do you mean that mass is only good to three decimal places? You can have as accurate a mass as you want but the answer, a force in Newtons, will only be good to 3 or 6 or however many decimal places in your least precise constant or measurement.

The most accurate that the gravitational constant has been measured is 6 digits. After that the measurements drift. So anything being done using G will have a result no greater than 6 significant digits.

This response has drifted at least 6 significant digits from your first response.
