Quick Answer
1 kg = 2.205 lbs. 1 lb = 453.6 g. 1 oz = 28.35 g. 1 metric tonne = 1000 kg = 2204.6 lbs. Mass is constant everywhere; weight depends on gravity.

Design Notes
Component weight matters for shipping cost calculations, vibration analysis, and aerospace applications. A loaded PCB typically weighs 50-500g. BOM weight estimation helps predict shipping costs early in product design.
Common Mistakes
- 1
Confusing avoirdupois ounces (28.35g, everyday use) with troy ounces (31.1g, precious metals).
- 2
Mixing up metric tonnes (1000 kg) with US short tons (907 kg) or Imperial long tons (1016 kg).
- 3
Using 'weight' when 'mass' is meant — they are different physical quantities (weight = mass × gravity).
Knowledge Base
1オンスは何グラム？
常衡オンス = 28.35g。トロイオンス（貴金属）= 31.10g。
1kgは何ポンド？
2.205ポンド。1ポンド = 453.6g。
メートルトンとは？
1t = 1000kg。米ショートトン = 907kg。英ロングトン = 1016kg。
質量と重量の違いは？
質量（kg）= 物質の量、普遍。重量（N）= 重力、場所により変化。
電子部品の重さは？
0402 SMD ≈ 1mg、0805 ≈ 10mg。実装済みPCB：50〜500g。
