The Scoville maths

The Scoville scale is linear: a pepper at 2,000,000 SHU has twice the capsaicinoids of one at 1,000,000 SHU. So the ratio is a simple division, 1,382,118 ÷ 1,176,182 ≈ 1.2×. Real pods vary, so the gap between any two fruits can be smaller or larger (1.2× to 1.3× across the measured ranges).
