2G

Each fully grown male, which weighed less than 2g and measured under 3cm, continued to carry the little tadpoles until they metamorphosed into froglets.

For example, if you compare the nutritional content of half a cup of vanilla ice cream with half a cup of vanilla gelato, the ice cream has 2g more fat.

A more recent study showed 2g of matcha in older people aged 60 to 85 improved sleep quality.

Dad-of-two Mr Mansfield tried to weigh a dose of the powder within a range of 60 milligrams to 300 milligrams using a scale that had a weighing range of 2g-5,000g, meaning he ended up consuming several grams.

"It weighs 9.5g, it's a heavy piece. A medieval penny would weigh about 1.2g, so that's about seven medieval pennies, so it wouldn't have been a peasant who owned that at the time."
