Definition of Gram
- Definition
- The gram (g) is a metric unit of mass equal to one thousandth of a kilogram. It is widely used for measuring small quantities, particularly in food labeling, chemistry, and laboratory work.
Although not an SI base unit, the gram is fully compatible with the SI system and remains one of the most commonly used mass units worldwide. - Exact factor
- 1 g = 0.001 kg = 0.0352739619 oz
- Examples
- • 250 g ≈ 8.82 oz
• 500 g = 0.5 kg
Definition of Pound
- Definition
- The pound (lb) is a unit of mass used mainly in the United States and a few other countries. The international avoirdupois pound is defined exactly as 0.45359237 kilograms.
Pounds are widely used for body weight, packaged goods, and engineering applications in imperial and US customary systems. - Exact factor
- 1 lb = 0.45359237 kg (exact)
- Examples
- • 150 lb ≈ 68.04 kg
• 200 lb ≈ 90.72 kg
About the Gram
Facts & Uses
- Metric unit equal to 1/1000 of a kilogram (10⁻³ kg). Although not an SI base unit itself, it is the most widely used mass unit in everyday metric practice.
- Standard for nutrition labels worldwide (protein, carbs, fat, sodium per serving), laboratory chemistry, and European cooking recipes.
- Used in postal rates (most countries outside the US), spice and herb measurements, and illicit drug weights in legal/medical literature.
- Subdivisions: milligram (pharmaceuticals), microgram (vitamins, hormones); multiples: kilogram, tonne.
Curiosities
- Originally defined in 1795 as the mass of 1 cubic centimeter of water at 4 °C (its density maximum) — an elegant link between length, volume, and mass that survives only as an approximation today.
- A standard paperclip weighs about 1 g; a US dollar bill ≈ 1 g; a raisin ≈ 0.5 g — useful for intuiting small masses.
- 1 g ≈ 0.0353 oz ≈ 0.00220 lb ≈ 15.43 grains.
- The gram is so practical that the SI Brochure recognizes it explicitly even though kilogram is the base unit — a rare case of pragmatism over purity.

About the Pound
Facts & Uses
- Primary unit of mass in US customary and imperial systems; defined as exactly 0.45359237 kilograms by the 1959 International Yard and Pound Agreement.
- Standard for body weight (US healthcare), retail food packaging, postal rates, and freight in the United States and parts of the Commonwealth.
- Used in sports (boxing/MMA weight classes, weightlifting plates), firearms (bullet weight in grains, where 7000 grains = 1 lb), and cooking (US recipes).
- Subdivisions: ounce (1 lb = 16 oz), grain (1 lb = 7000 gr); multiples: stone (UK, 14 lb), hundredweight, short ton (2000 lb).
Curiosities
- The symbol "lb" comes from the Latin libra pondo ("a pound by weight"), the same root as the British currency pound sign £.
- Historically, dozens of regional pounds existed across Europe (Tower pound, merchant's pound, troy pound); the 1959 Agreement standardized the avoirdupois pound for English-speaking nations.
- The troy pound (used for precious metals) is different — 1 troy lb = 12 troy oz = 373.2417216 g, lighter than the avoirdupois pound.
- 1 lb = exactly 453.59237 g — one of the few imperial-to-metric conversions defined to perfect precision.
