Achoimriú

Tá mona nó píosa airgid eile san íomhá seo chun toise a thaispeáint. Ná húsáid boinn mar scála, os rud é go gcaithfidh duine nach bhfuil aithne acu ar an mona i gceist toisí an mhona a chuardú nó a thomhas. Mar thoradh, tá boinn neamhúsáideach don fheidhm seo. Chomh maith, má úsáidtear boinn i ngrianghraf, treisítear claontacht geografach, agus tá cóipcheart ar dhearadh boinn éigin. Go hidéalach, cuirtear rialóir i ngrianghraf in aice leis an suibiacht (mar a fheictear sa ghrianghraf seo) nó cuirtear marcáil scála leis an ngrianghraf le eagarthóir íomhá (mar a fheictear sa ghrianghraf seo). Na haonaid is coitianta timpeall an domhain ná na haonaid SI agus an córas meadrach. Samplaí droch-chleachtas: anseo.
