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
Quantos gramas em uma onça?
Avoirdupois: 28,35 g. Troy (metais preciosos): 31,10 g.
Quantas libras em um kg?
1 kg = 2,205 lbs. 1 lb = 453,6 g.
O que é tonelada métrica?
1 t = 1000 kg. Tonelada curta US = 907 kg.
Diferença massa e peso?
Massa (kg) = matéria, constante. Peso (N) = força gravitacional.
Peso de componentes eletrônicos?
0402 SMD ≈ 1 mg, 0805 ≈ 10 mg. PCB montada: 50–500 g.
