Ruler (scale) par do tarah ke measurements hote hain: ek taraf inches aur dusri taraf centimeters. Mathematics aur tailoring mein aksar inch ko cm mein convert karne ki zarurat padti hai.
1 Inch exactly 2.54 cm ke barabar hota hai.
1 Foot mein 12 inches hote hain.
Agar cm se inch mein badalna ho, toh number ko 2.54 se divide (bhag) karte hain.
1 Inch = 2.54 Centimeters (CM)
Yeh ek universally accepted standard value hai. Jab bhi aap kisi value ko inches se cm mein convert karna chahein, toh us number ko simply 2.54 se multiply kar dein.
Kuch common conversions is prakar hain:
1 centimeter mein lagbhag 0.3937 inches hote hain. (1 ÷ 2.54 = 0.3937).
