I live in London. We weigh stuff up in grams, ounces (28g) and kilos (1000g,36oz) and we have a 9bar (9oz, quarter Kilo), half bar, Q.B (quarter bar), or a Que (7gram, quarter oz), eighth (3.5g, eighth of oz). These are our markers so to speak.
Can someone explain how this compares with American...
