Steel-Cut Oats: US Cups to Grams (g) & Cooked Volume Conversion
Convert volumes of uncooked steel-cut oats (also known as Irish or pinhead oats) measured in US cups to its approximate weight in metric grams (g) and estimate the resulting cooked volume.

Important Considerations for Steel-Cut Oats:
Steel-cut oats are denser than rolled oats. The weight of 1 US cup of uncooked steel-cut oats is typically around **150-160 grams** (approximately 5.3-5.6 ounces).
When cooked with liquid (e.g., water or milk), steel-cut oats generally expand to about **3 to 4 times their original volume**, depending on the amount of liquid used and desired consistency. They require a longer cooking time than rolled oats.
This chart refers to traditional steel-cut oats. Quick-cooking steel-cut oats might have slightly different characteristics.
For consistent results, especially for portion control or recipes, measuring steel-cut oats by weight can be beneficial.
