1 ইঞ্চি = 25.4 মিমি
উদাহরণ: আপনি যদি একটি মার্কিন থ্রেড রূপান্তর করতে চান(আমেরিকান থ্রেড) 10 ইঞ্চি একটি ব্যাস সঙ্গে aমেট্রিক থ্রেড, আমরা সহজভাবে ব্যাসকে 25.4 দ্বারা গুণ করতে পারি, যা 10 × 25.4 = 254 মিমি; যদি আমরা 10 মিমি ব্যাসের একটি মেট্রিক থ্রেডকে রূপান্তর করতে চাই আমেরিকান থ্রেড তৈরি করার জন্য, আমাদের শুধুমাত্র এর ব্যাসকে 25.4 দ্বারা ভাগ করতে হবে, যা 10÷25.4=0.3937 ইঞ্চি।
