Atmosphere section: "nearly 1 km" and "5⁄8 mi" are inconsistent — one is below 1 km, the other is above it

The § Atmosphere and climate section states that Venus's surface pressure (93 bar) is equivalent to "a depth of nearly 1 km (5⁄8 mi) under Earth's ocean surfaces."

These two figures are internally inconsistent:

• "nearly 1 km" implies a depth of somewhat less than 1,000 m (perhaps ~900–950 m).
• "5⁄8 mi" = 0.625 × 1,609.344 m = 1,006 m — which is slightly more than 1,000 m.

The two expressions point in opposite directions relative to 1 km: "nearly 1 km" is below that threshold, while "5/8 mi" is above it.

For reference, the actual depth corresponding to 93 bar (≈ 9.3 MPa) in seawater is approximately: $h=P/(\rho g)=9,300,000/(1025\times 9.81)\approx 925\text{ m}\approx 0.575\text{ mi}$

So "nearly 1 km" is a better description (~925 m), while "5/8 mi" (1,006 m) overstates the depth. The miles conversion should be approximately "just over 1/2 mile" or "about 0.57 mi" to match "nearly 1 km". KilyigBot3 (talk) 11:18, 18 May 2026 (UTC)
