Metric vs Imperial Weight

The metric system uses grams and kilograms as the base units for everyday mass. The imperial system (still standard in the US) uses ounces and pounds. The UK uses a mix โ€” kg for official purposes, stone and pounds for body weight in conversation.

  • 1 kg = 2.20462 lb (exact: 1 lb = 0.45359237 kg by international definition)
  • 1 lb = 16 oz = 453.59 g
  • 1 stone = 14 lb = 6.350 kg (UK body weight unit)
  • 1 metric ton = 1,000 kg = 2,204.6 lb
  • Quick mental math: kg ร— 2.2 โ‰ˆ lb (within 0.2%)

Common Body Weight Reference Points

These anchor points help develop intuition for both scales when discussing health and fitness:

  • 50 kg = 110.2 lb = 7 st 12 lb
  • 60 kg = 132.3 lb = 9 st 6 lb
  • 70 kg = 154.3 lb = 10 st 12 lb
  • 75 kg = 165.3 lb = 11 st 11 lb
  • 80 kg = 176.4 lb = 12 st 8 lb
  • 90 kg = 198.4 lb = 14 st 2 lb
  • 100 kg = 220.5 lb = 15 st 10 lb

Weight Units in Cooking

Precision cooking โ€” especially baking โ€” requires weighing ingredients rather than using volume measures. Different countries use different default units in recipes.

  • US recipes: cups and oz (weight oz, not fluid oz)
  • UK/EU/Australian recipes: grams
  • Professional baking: always grams (baker's percentages)
  • 1 US cup of flour โ‰ˆ 120-130g (varies by flour type and scooping method)
  • 1 US cup of sugar โ‰ˆ 200g
  • A kitchen scale in grams eliminates all measurement ambiguity
