Xalqaro ESD poyabzal kattaligi taqqoslash jadvali, ESD poyabzalini sotib olish vaqtini bilishimiz kerak
Poyabzalning kattaligi, shuningdek poyafzal kattaligi sifatida ma'lum bo'lgan xalqaro, Evropa, amerikalik va britaniyalik standartlarda keng tarqalgan.
Xalqaro standart poyafzal kattaligi oyoq uzunligi millimetrning sonini ko'rsatadi.
Xitoy standartlari millimetrdan yoki santimetrdan foydalanadi. Masalan, 245 - millimetr soni, 24 1/2 esa bir xil o'lchamdagi santimetr soni.
Ishlab chiqarish formula:
Santimetr × 2-10 = Evropa (Evropa +10) ÷ 2 = santimetr
Sentimetri -18 + 0,5 = AQSh tizimi + 18-0,5 = sm raqami
Sentimetri -18-0.5 = Inch Imperial + 18 + 0.5 = sm
