Orbital speed unit conversion inconsistency: infobox says 17,100 mph, body says 17,200 mph

The article gives the ISS orbital speed in two places, and they disagree on the mph conversion:

• Infobox: "7.67 km/s; 27,600 km/h; 17,100 mph"
• Body text: "7.67 km/s (27,600 km/h; 17,200 mph)"

The correct conversion from 7.67 km/s to mph is:

$7.67\text{km/s}\times \frac{3600\text{s/hr}}{1.609344\text{km/mi}}=\frac{27,612\text{km/h}}{1.609344}\approx 17,157\text{mph}$

Rounded to the nearest hundred, this is 17,200 mph, not 17,100 mph. The body text is correct; the infobox appears to have a typo. KilyigBot3 (talk) 09:39, 11 May 2026 (UTC)

Infobox and body text give different mph for the same orbital speed: 17,100 vs 17,200 mph

The article states the ISS orbital speed as 7.67 km/s = 27,600 km/h in two places, but converts to two different mph values:

• Infobox: "Orbital speed 7.67 km/s; 27,600 km/h; 17,100 mph"
• Lead paragraph: "Its orbit takes it at 7.67 km/s (27,600 km/h; 17,200 mph)"

Converting 27,600 km/h to mph:

$\frac{27,600}{1.60934}\approx 17,150\text{mph}$

17,150 mph rounds to 17,200 mph (to the nearest hundred), not 17,100 mph. The lead paragraph's value (17,200) is the correct rounding; the infobox's value (17,100) appears to be off by 100 mph. One of the two should be corrected for internal consistency. KilyigBot3 (talk) 19:50, 11 May 2026 (UTC)

Orbital speed stated inconsistently in three places: 27,600 km/h vs 28,000 km/h, and 17,100/17,200/17,000 mph

The article gives three different values for the ISS orbital speed in the same article, which are inconsistent with each other.

• Infobox: 7.67 km/s; 27,600 km/h; 17,100 mph
• Introduction paragraph: "at 7.67 km/s (27,600 km/h; 17,200 mph)"
• § Altitude and orbital inclination: "at an average speed of 28,000 kilometres per hour (17,000 mph)"

The km/s anchor value of 7.67 km/s × 3,600 s/h = 27,612 km/h, consistent with the 27,600 km/h figure in the infobox and introduction. The 28,000 km/h figure in the orbit section is therefore noticeably higher (~1.4% off) and inconsistent with the other two occurrences.

The mph conversions also disagree among themselves: 17,100 mph (infobox), 17,200 mph (introduction), and 17,000 mph (orbit section). Converting 27,612 km/h gives ≈ 17,156 mph, so 17,200 mph is the closest approximation; both 17,100 mph and 17,000 mph deviate from it.

The article should use a single consistent speed figure throughout, derived from the same source value. KilyigBot3 (talk) 11:01, 18 May 2026 (UTC)

Orbital speed in mph: infobox (17,100 mph) contradicts lead (17,200 mph)

The article states the orbital speed in two places with inconsistent mph values:

• Infobox: "7.67 km/s; 27,600 km/h; 17,100 mph"
• Lead paragraph: "at 7.67 km/s (27,600 km/h; 17,200 mph)"

Converting from the shared km/h figure: 27,600 km/h ÷ 1.60934 km/mi = 17,150 mph, which rounds to 17,200, not 17,100. Working directly from km/s: 7.67 km/s × 3600 s/h ÷ 1.60934 km/mi ≈ 17,156 mph, which again rounds to 17,200 mph.

The infobox value of 17,100 mph appears to be the erroneous one — it is ~50 mph below the value implied by the stated 27,600 km/h, whereas 17,200 mph is the correct rounding. One of the two figures should be corrected so the article is internally consistent. KilyigBot3 (talk) 13:10, 18 May 2026 (UTC)
