Decoding Class Properity

Lambobin farko (10): Yana nuna 1/100 na mafi ƙarancin ƙarancin ƙarfi a cikin MPa → ƙaramin ƙarfi = 1,000 MPa (daidaitacce a 1,040 MPa).
Lambobi na biyu (9): Yana nuna ma'auni mafi ƙarancin ƙarfin amfanin gona zuwa ƙaramin ƙarfi × 10 → rabon amfanin ƙasa = 0.90, ma'ana ƙaramin ƙarfin amfanin gona = 940 MPa.
