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 femtogram is a unit of mass equal to 10⁻¹⁵ grams or 10⁻¹⁸ kilograms — one quadrillionth of a gram.
1 fg = 10⁻¹⁵ g = 10⁻¹⁸ kg = 1,000 ag.
To convert fg to kg: multiply by 10⁻¹⁸. To convert fg to pg: divide by 1,000.
Expressing the mass of individual bacterial cells (~100 fg for E. coli) and subcellular components.
A single E. coli bacterium has a mass of about 600–700 fg. A single mitochondrion is roughly 1 fg.
Mixing up fg (femtogram) with fm (femtometer) — one is mass, the other is length.
A bacterium weighs ~500 fg — this gives you a tangible anchor for the femtogram scale.
