''The typical ground temperature of a burial plot in Chicago depends on the depth and the season. According to the Illinois State Climatologist Office, the average soil temperature at 4 inches depth ranges from about 25°F in January to about 75°F in July. The average soil temperature at 8 inches depth ranges from about 30°F in January to about 77°F in July. These measurements are made under grass, so the soil temperature under other ground covers or under bare ground may vary somewhat from those shown here. In the winter, when the ground is frozen, cemeteries are able to continue burying the dead by using special equipment such as frost rippers or steamers to break through the frozen layer of soil. They also use heaters or blankets to keep the graves open until the burial service is completed.''

Planck Length here actually refers to the length of Planck himself. The same may apply to other names. 2659: Unreliable Connection (talk) 03:02, 25 May 2023 (UTC)
- And here I was thinking it meant the length of Planck planking. Thisfox (talk) 22:00, 25 May 2023 (UTC)
I wonder if this is alluding to the Smoot, a unit of measure devised by MIT students to represent the height of Oliver R. Smoot. Probably worth a mention in the description nonetheless. Trimeta (talk) 03:45, 25 May 2023 (UTC)
Hawking radiation: ~100 W (through heat)
Planking is a thing.https://en.m.wikipedia.org/wiki/Planking_(fad) One pretends that one is a board, or plank. Are some funny pics. The opposite of planking would be good god how? How can even a cat!?!! [Special:Contributions/172.69.58.161|172.69.58.161]] 06:26, 25 May 2023 (UTC)
Hubble length is 13.2 m. 141.101.98.64 10:30, 25 May 2023 (UTC)
The m³ unit for Broca's area is surely a typo, right? 162.158.94.47 14:55, 25 May 2023 (UTC)
Just a couple of others: 1 Watt is what it takes to invent the condensing steam engine and Euler's number doesn't exist, because he died before telephones were invented. 172.69.247.45 15:08, 25 May 2023 (UTC)
- There are lots of <someone>'s Number constants. We could have an entire phonebook of these. Barmar (talk) 17:53, 25 May 2023 (UTC)
- I tried phoning Graham's Number, once. I'm still not yet finished dialling! 172.70.91.186 19:22, 25 May 2023 (UTC)
- I thought you meant Alexander Graham Bell's number. 172.69.22.129 23:04, 25 May 2023 (UTC)
- I tried phoning Graham's Number, once. I'm still not yet finished dialling! 172.70.91.186 19:22, 25 May 2023 (UTC)
- Chandresekhar's Limit = 3 pints? Barmar (talk) 17:53, 25 May 2023 (UTC)
- Don't forget that numbers are now Euler letters! 172.70.85.137 20:41, 25 May 2023 (UTC)
From a friend, regarding Fermi's current temperature: The typical ground temperature of a burial plot in Chicago depends on the depth and the season. According to the Illinois State Climatologist Office, the average soil temperature at 4 inches depth ranges from about 25°F in January to about 75°F in July. The average soil temperature at 8 inches depth ranges from about 30°F in January to about 77°F in July.
