If a measuring instrument, say, a ruler, has a resolution of 1cm, the reading of any object is accurate to +/- 0.5 of a centimetre. Is there any terminology to describe 0.5 in this context? I’m tempted to call it uncertainty (of 0.5), but I’m not sure this is right.

The term "error" or "maximum error" is commonly used. – user247327
