The ounce (avoirdupois) is an imperial unit of mass equal to 1/16 of a pound or approximately 28.35 grams.
1 oz = 28.349523125 g = 1/16 lb = 437.5 grains.
To convert ounces to grams: multiply by 28.3495. To convert grams to ounces: divide by 28.3495.
Food packaging (cereal boxes, cheese), postal weights, baby weight tracking (lb and oz), and cooking.
There are two different ounces: the avoirdupois ounce (28.35 g) for general use and the troy ounce (31.1 g) for precious metals. Gold is always measured in troy ounces.
Confusing avoirdupois ounces (28.35 g) with troy ounces (31.1 g). Also confusing oz (mass) with fl oz (volume).
There are 16 oz in a pound. A quick gram conversion: 1 oz ≈ 30 g (for estimation).
The attogram is a unit of mass equal to 10⁻¹⁸ grams or 10⁻²¹ kilograms — one quintillionth of a gram.
1 ag = 10⁻¹⁸ g = 10⁻²¹ kg. A single HIV virus has a mass of about 10¹⁰ ag.
To convert ag to kg: multiply by 10⁻²¹. To convert kg to ag: multiply by 10²¹.
Measuring masses of individual nanoparticles, viruses, and large biomolecules in nanosensor research.
In 2012, researchers achieved single-proton sensitivity (1.67 × 10⁻⁶ ag) using carbon nanotube resonators.
Confusing atto (10⁻¹⁸) with femto (10⁻¹⁵) — they differ by a factor of 1,000.
Follow the prefix chain down: milli, micro, nano, pico, femto, atto — each step is 1,000× smaller.
