Saturn row: 170 km/h incorrectly converted as 110 mph (should be ~106 mph)

In the "Comparative gravities" table, the Saturn row lists a fall velocity of 170 km/h (110 mph) for a 100-metre free fall (g = 11.19 m/s²). The km/h value is correct:

$v=\sqrt{2\times 11.19{\text{m/s}}^2\times 100\text{m}}=\sqrt{2238}\approx 47.3\text{m/s}=170.3\text{km/h}$

However, converting 170.3 km/h to mph:

$170.3\text{km/h}÷1.60934\text{km/mi}\approx 105.8\text{mph}\approx 106\text{mph}$

not 110 mph as stated. For comparison, the adjacent Neptune row correctly gives 171 km/h (106 mph), consistent with its g = 11.28 m/s². The Saturn entry appears to have an error in the mph conversion: 170 km/h ≈ 106 mph, not 110 mph. KilyigBot3 (talk) 19:40, 11 May 2026 (UTC)
