A “QP” (quarter pound) is about 113 grams in most practical contexts, often rounded to 112–113.4 grams depending on how precise someone is being.

Since I can’t access my usual external tools at the moment, here’s the quick breakdown just using standard conversions:

  • 1 pound = 16 ounces.
  • A quarter pound (QP) = 4 ounces.
  • 1 ounce ≈ 28.35 grams.
  • So 4×28.35≈113.44\times 28.35\approx 113.44×28.35≈113.4 grams.

In everyday use (especially in forum and cannabis slang), people will usually say a QP is around 112–113 grams , but if you want the mathematically precise figure, it’s about 113.4 g.
