Luggage allowances
Airline baggage rules are a common reason people convert weight:
- Domestic India (economy): typically 15 kg check-in plus 7 kg cabin, though limits vary by airline and fare type.
- International economy: often 23 kg (50 lb) per bag on piece-concept routes such as the US and Canada, or a total weight such as 30 kg on many other routes.
- Bags over 23 kg (50.7 lb) usually count as overweight on piece-concept routes, and bags over 32 kg (70 lb) are generally not accepted as normal checked baggage.
Always check your airline’s current baggage policy for your specific ticket.
Body weight in stones (UK)
In the UK, body weight is often given in stones and pounds: 1 stone = 14 lb = 6.35 kg. So 70 kg = 154.3 lb = 11 st 0.3 lb. To convert: divide total pounds by 14 for the stones, and the remainder is pounds.
Mass vs weight
Strictly speaking, kilograms measure mass (how much matter), while weight is the force of gravity on that mass, measured in newtons. A 60 kg person has a weight of about 588 N on Earth and only about 97 N on the Moon, but their mass is 60 kg in both places. In everyday life, and in this converter, “weight” means mass.
Small units: grams, milligrams and micrograms
- Medicine strengths are in milligrams (a 500 mg paracetamol tablet = 0.5 g).
- Vitamins such as B12 and D are often in micrograms (mcg or µg): 1 mg = 1,000 mcg.
- Vitamin D is also given in IU: 1,000 IU of vitamin D3 = 25 mcg. IU conversions differ for every vitamin, so check before converting.
Indian traditional units
Gold is priced per 10 grams in India. The traditional tola (about 11.66 g) is still used by some jewellers. A quintal (100 kg) is the standard unit for agricultural produce and minimum support prices (MSP). One metric tonne = 10 quintals = 1,000 kg.
