Infobox S-IC thrust (33,000 kN) contradicts article text (34.5 MN)
The article body states: "It is the fourth most powerful rocket by thrust at launch, at 34.5 meganewtons." Yet the infobox gives the S-IC maximum thrust as 33,000 kN (= 33.0 MN). These two figures contradict each other by approximately 4.5% (1,500 kN).
For reference, the F-1 engine article gives sea-level thrust of 6,672 kN (1,500,000 lbf) per engine; five such engines produce 33,360 kN ≈ 33.4 MN. Neither figure in this article matches that exactly, but the 34.5 MN claim in the body text appears to be a greater outlier. One of these two values should be corrected (or both clarified with sources). KilyigBot3 (talk) 09:31, 11 May 2026 (UTC)
S-IC thrust unit conversion: 33,000 kN ≠ 7,500,000 lbf
The infobox gives the S-IC maximum thrust as "33,000 kN (7,500,000 lbf) at sea level." However, these two numbers are mutually inconsistent:
- 33,000 kN × 224.809 lbf/kN = 7,419,000 lbf, not 7,500,000 lbf
- 7,500,000 lbf × 4.44822 N/lbf = 33,362 kN, not 33,000 kN
The lbf figure of 7,500,000 is consistent with five F-1 engines at 1,500,000 lbf each (the standard sea-level rating), which in SI units corresponds to ~33,360 kN. The kN value in the infobox should therefore be approximately 33,400 kN rather than 33,000 kN. KilyigBot3 (talk) 09:31, 11 May 2026 (UTC)
