2:21 PM · Oct 25, 2022 @isostandards Is there a calculation of a standard unit of infinitesimal time? Planck’s 1899 figure is 5.391247(60)×10−44 seconds. Stoney’s 1874 figure is 4.6054×10−45 seconds. It would be good to have the ISO address this discrepancy. https://81018.com/iso/ (this page)

Note: It would also be helpful if there were a discussion about the possibilities of what is being manifest at that time. That is, given our understanding of dimensionless constants, could an infinitesimal sphere be defined by those basic units? -BEC

To whom it may concern:

Are the (1) xonosecond, (2) vecosecond,  (3) mecosecond, (4) duecosecond, (5) trecosecond, and (6).tetrecosecond all officially recognized names for the infinitesimal time scales between the yoctosecond and the Planck Second? If not, is the ISO considering formally naming these number groups?

Thank you.

Most sincerely,


PS. Here is how these are displayed within Wikipedia:

  • One yoctosecond = 1×10-24 The yoctosecond is formally recognized.
  • One xonosecond = 1×10-27 In question.
  • One vecosecond = 1×10-30 In question.
  • One mecosecond = 1×10-33 In question.
  • One duecosecond = 1×10-36 In question.
  • One trecosecond 1×10-39 In question.
  • One tetrecosecond = 1×10-42 In question.
  • Planck Time = 5.391×10-44 Formally recognized.

Dr. John Walter, ISO, President, 2018-2020 from Standards Council of Canada (SCC-CCN), 55 Metcalfe Street, Suite 600, Ottawa, ON  K1P 6L5  Canada

Dear Dr. John Walter:

Congratulations on a life dedicated to understanding the basics!

I am intrigued with the reformulation of the kilogram and have thought a bit about standards. Might ISO consider the reformulation for time (a second) and length (a meter)? It seems the Planck units could be involved. I’ve written a little about it here: https://81018.com/formulas/

Would you recommend any of the experts in your sphere of influence who might be able to guide our thinking properly? Thank you.


Note: On July 25, 2022 a note was sent to SCC to ask about the CCN in the logo:

“CCN is in your logo yet there is no indication for what that abbreviation is. I assume it is a translation into French of the SCC yet it would be nice to see that in print. I investigated here, yet they have no listings for Canada. Respecting your French-speaking population, I believe it should be explained. Thank you.”

Great fun, Clare. Thanks for writing that article!

Such understatement when you write: “Standardized measurement literally makes the world go around. It is necessary for many diverse fields, including science and engineering, and is essential for new inventions and supporting innovation in both industry and society” (our emphasis).

I think there is at least a triple entendre in there! And, it is such an understatement, I would say that it is almost cheeky!

We’re high school people using the the Planck base units to define seconds, length, mass, and charge with dimensionless constants. We think it is the simplest way to check calibrations.

Want to see the universe mathematically mapped in just 202 doublings?

Even after over seven years, it still blows us away.

Thanks again for your writings about the ISO!
