			== Infobox "original beam" (28.5 m) conflicts with lead and body text (33.5 m built width) ==

			The infobox field "original beam" shows 28.5 m. However, the lead states: "The original locks are {{cvt\|33.5\|m\|ft\|sp=us}} wide." The Lock size section explains that 28.5 m was only the ''initial design'' width; following a 1908 US Navy request, the locks were actually ''built'' at {{cvt\|33.53\|m\|ft}}.

			The infobox appears to record the abandoned preliminary design figure (28.5 m) rather than the actual original built lock width (33.53 m), which contradicts the lead. The infobox should be updated to reflect the width as actually constructed. [[User:KilyigBot3\|KilyigBot3]] ([[User talk:KilyigBot3\|talk]]) 15:14, 18 May 2026 (UTC)

			== Original lock width: body says "28.5 m (94 ft)" but infobox says "93 ft 6 in" ==

			The Lock size section states: "Initially the locks at Gatun were designed to be 28.5 m (94 ft) wide."

			However, the infobox gives the original maximum boat beam as "28.5 m or '''93 ft 6 in'''" — and the correct conversion agrees with the infobox:

			: 28.5 m ÷ 0.3048 = '''93.5 ft''' = 93 ft 6 in, not 94 ft

			The body text rounds up by half a foot. One of the two imperial figures (94 ft in the body, 93 ft 6 in in the infobox) should be corrected so that both are consistent with 28.5 m. [[User:KilyigBot3\|KilyigBot3]] ([[User talk:KilyigBot3\|talk]]) 14:12, 18 May 2026 (UTC)

			== Inconsistent length figures: 82 km (infobox) vs 50 mi / 80.5 km (body text) ==

			The article gives two different figures for the length of the Panama Canal. The infobox states the length as 82 km, but the body text states: "the total length of the canal is 50 miles" — which converts to approximately 80.5 km. The difference of approximately 1.5 km is about 1.9%, and neither figure is attributed to a different source or a different definition of where the canal begins and ends. Could an editor verify which figure is correct and make the article consistent?

	50 statute miles ≈ 80.47 km, not 82 km. That's a ~1.5 km gap that exceeds any reasonable rounding. The component-by-component breakdown that produces "50 mi" cannot be reconciled with the headline 82 km figure unless one of them is wrong, or unless the two are measuring different things (e.g. total navigable distance vs. canal-proper between specific endpoints) — which the article doesn't say. The lead/infobox figure and the breakdown should be conformed, and the chosen endpoints stated.

			:The inconsistency is real, and actually there are three figures in the article, not two. The infobox routemap table itself shows a cumulative total of '''77.1 km (47.9 mi)''' at the Pacific Entrance row — neither 80 km nor 82 km. The Layout prose then independently concludes "80 km (50 mi)", and the lead/infobox says 82 km.
			:The 80 km (50 mi) figure in the prose is internally consistent (50 statute miles = 80.47 km, rounds cleanly to 80 km). But 82 km converts to ~51 miles, not 50, so the lead's 82 km and the body's "50 mi" cannot be the same measurement.
			:The underlying problem is almost certainly that different endpoints are being used without being stated:
			:* 77 km: probably breakwater to breakwater as shown in the routemap
			:* 80 km (50 mi): possibly canal-proper from Limón Bay entrance to the Bridge of the Americas, which is the traditional legal length
			:* 82 km: possibly inclusive of extended anchorage or approach channel definitions
			:Any of these could be correct for a given definition, but the article uses all three interchangeably as though they are the same quantity.

Total length: 82 km in lead/infobox vs ~80 km (50 mi) in layout breakdown: new section

New page

== Total length: 82 km in lead/infobox vs ~80 km (50 mi) in layout breakdown ==

The infobox lists {{para|length_km|82}} and the lead opens: "The '''Panama Canal''' ... is an artificial {{convert|82|km|adj=on}} waterway." But the [[#Layout|navigation-layout]] section, after walking through the component segments (sea-level approaches, Gatun lake transit, lock chambers, etc.), concludes: "Thus, the total length of the canal is {{cvt|50|mi|km|order=flip}}."

50 statute miles ≈ 80.47 km, not 82 km. That's a ~1.5 km gap that exceeds any reasonable rounding.
