API Gravity Blend

Predicts the API gravity you get when two crude streams share one tank. Gravity does not blend linearly in API degrees — this tool converts each stream to specific gravity, weights by volume fraction, and converts back, the way a terminal operator or scheduler checks a blend before committing it to a railcar or pipeline batch.

Enter each stream's API gravity and its volume (any consistent unit) — the blended gravity updates live.

All results are an engineering estimate — not for custody transfer. Field measurement and certified tables govern.
