Although the numeric location gets more precise as you add more numbers - if they only get 3 decimal places, that's about 110x80m in the UK.
If you use degrees, minutes and seconds, you only need 6 numbers to get ~30x20m in the UK (and a decimal place on the seconds brings it down to ~3x2m - the same as W3W.)
