Oson esda qolish uchun maslahatlar

• 1 kg ≈ 2,2 lb (tezkor hisob-kitob uchun)
• 1 lb ≈ 454 g
• 1 untsiya ≈ 28,35 g
• 1 stone = 14 lb = 6.35 kg (used in UK for body weight)
• 1 tonna = 1000 kg ≈ 2205 lb
• 1 qisqa tonna (AQSh) = 2000 lb ≈ 907 kg
• 1 uzun tonna (Britaniya) = 2240 lb ≈ 1016 kg
• 1 greyn ≈ 64,8 mg (ballistika va farmatsiyada qo'llaniladi)

Mass vs Weight

Kundalik hayotda “og'irlik” va “massa” sinonim sifatida ishlatiladi, ammo ular farq qiladi:

• Mass (kg, lb-massa) — moddaning miqdori, hamma joyda o'zgarmas
• Weight (N, lbf) — tortishish kuchi — joylashuvga qarab o'zgaradi
• On Earth’s surface: Weight (N) = Mass (kg) × 9.81 m/s²
• 100 kg massali jism Yerda 981 N, Oyda esa atigi 163 N tortadi

Qo'llanish sohasiga xos o'lchov birliklari

• Balanslash: Unbalance measured in g·mm (grams × millimeters) or oz·in (ounces × inches)
• Pharmacy: Greynlar (1 gr = 64,8 mg), dram, skrupul
• Qimmatbaho metallar: Troy unsiyasi (31.103 g) ≠ Avoirdupois unsiyasi (28.350 g)
• Gemstones: Karat (1 ct = 0.2 g)
