Mutengo wekuchekazvinoreva huwandu hwehukuru hwegirazi hunodiwa mushure mekuchekwa kwegirazi risati raporishwa.
Fomura iyi igirazi rakakwana rine saizi inodiwa x kureba kwegirazi kunodiwa x upamhi hwegirazi hunodiwa / kureba kwepepa regirazi risina kugadzirwa / upamhi hwepepa regirazi risina kugadzirwa = mwero wekucheka
Saka pakutanga, tinofanira kunzwisisa zvakajeka saizi yegirazi rakajairika uye kuti mamirimita mangani (mm.) anofanira kusiya pahurefu nehupamhi hwegirazi pakucheka:
