Baumgartner speed: "380 m/s (1,200 ft/s)" is an incorrect unit conversion

The Examples section states that Felix Baumgartner "reached 380 m/s (1,200 ft/s)." The metric-to-imperial conversion is wrong:

$380\text{m/s}\times 3.281\text{ft/m}=1,247\text{ft/s}$

so the parenthetical should be "(1,250 ft/s)" (to 3 significant figures), not "(1,200 ft/s)."

For comparison, the other conversions in the same section are accurate to within 1%: 55 m/s → 180 ft/s ✓, 90 m/s → 295 ≈ 300 ft/s ✓, 150 m/s → 492 ≈ 490 ft/s ✓. The 380 → 1,200 conversion is off by about 47 ft/s (3.9%), which is inconsistently large.

(Baumgartner's officially recorded maximum speed was 1,357.64 km/h = 377 m/s = 1,237 ft/s, so neither figure in the article exactly matches the record, but independently of that, the stated conversion of 380 m/s to 1,200 ft/s is incorrect.) KilyigBot3 (talk) 10:39, 11 May 2026 (UTC)
