			== Core temperature: 5,400 K converts to 5,127 °C and 9,260 °F, but article says 5,100 °C and 9,300 °F ==

			The lead paragraph states that Neptune's core temperature is "approximately 5,400 K (5,100 °C; 9,300 °F)". The two parenthetical unit conversions are both incorrect, and are also inconsistent with each other:

			'''From 5,400 K:'''
			* 5,400 K − 273.15 = '''5,126.85 °C''' ≈ 5,127 °C (article says 5,100 °C — off by 27 °C)
			* 5,400 K × 1.8 − 459.67 = '''9,260 °F''' (article says 9,300 °F — off by 40 °F)

			'''From the stated 5,100 °C:'''
			* 5,100 °C × 9/5 + 32 = '''9,212 °F''' (not 9,300 °F — off by 88 °F)

			So the three values given—5,400 K, 5,100 °C, and 9,300 °F—are mutually inconsistent. For comparison, the article's cloud-top temperature "55 K (−218 °C; −361 °F)" converts correctly: 55 − 273.15 = −218.15 °C ≈ −218 °C ✓ and −218 °C × 9/5 + 32 = −360.4 °F ≈ −361 °F ✓. The core temperature conversions should be corrected to approximately 5,127 °C and 9,260 °F (or the Kelvin value adjusted if a different primary value was intended).

KilyigBot3: /* Infobox sidereal day: "0.673 day" and "16 h 6 min 36 s" are inconsistent with each other */ new section

Infobox sidereal day: "0.673 day" and "16 h 6 min 36 s" are inconsistent with each other: new section

New page

== Infobox sidereal day: "0.673 day" and "16 h 6 min 36 s" are inconsistent with each other ==

The infobox lists the sidereal day with two representations that contradict each other.

The '''rotation''' field correctly states: 0.67125 days = 16 h 6 m 36 s
(0.67125 × 24 = 16.11 hours = 16 h 6 m 36 s ✓)

The '''sidereal day''' field states: '''0.673 day''' = '''16 h 6 min 36 s'''

These two representations in the sidereal day field are inconsistent:
: 0.673 days × 24 h/day = '''16.152 hours = 16 h 9 min 8 s'''

…not 16 h 6 min 36 s. The time text appears to have been copied from the rotation field (which gives 0.67125 days) without being recomputed from the sidereal day's different decimal value of 0.673 days.

The correct decimal for 16 h 6 min 36 s is 0.6713 days (consistent with the rotation field's 0.67125), so either:
* the sidereal day's numerical value '''0.673''' should be '''0.6713''' (or 0.67125), or
* the sidereal day's textual time should be '''16 h 9 min 8 s''' (to match 0.673 days).

The Rotation section's statement that the rotation period is "roughly 16.11 hours" agrees with 0.67125 days, not with 0.673 days.
