To convert ounces to grams: multiply by 28.3495. To convert grams to ounces: divide by 28.3495.
1 oz = 28.349523125 g = 1/16 lb = 437.5 grains.
For example, 1 Ounce (oz) = 2.834952e-11 Teragram (Tg).

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 teragram equals 10¹² grams or one million tonnes (one megatonne).
1 Tg = 10¹² g = 10⁹ kg = 10⁶ tonnes = 1 megatonne.
To convert Tg to tonnes: multiply by 10⁶. To convert Tg to Gg: multiply by 1,000.
Global carbon budgets (~10,000 Tg C/year from fossil fuels), volcanic eruption plume masses.
Earth's atmosphere has a total mass of about 5.15 × 10⁶ Tg (5.15 × 10¹⁸ kg).
Confusing Tg with Pg (petagram): 1 Pg = 1,000 Tg. Climate papers use both — check carefully.
Global CO₂ emissions ≈ 36,000 Tg/year (or 36 Pg/year). This is a key climate number to remember.
