Uniformity of kts and mph wind speed ranges in TCWS

Good day to all. I would like to point out the non-uniformity across Wikipedia articles and templates on the wind speed ranges of the Philippine TCWS, particularly the wind speeds in knots (kts) and miles per hours (mph).

I'm one of the contributors of the article on Tropical Cyclone Wind Signals. And in that article, I indicated the wind speed ranges in kilometers per hour (km/h), meters per second (m/s) and knots (kts) based on how DOST-PAGASA laid out these wind speed ranges in the March 2022 revision of the TCWS system—which, in turn, has been based on the Beaufort wind force scale, with the exception of Wind Signal #5.^[a]^[1]^[2]^[3] Since the km/h, m/s and kts wind speed ranges are based on the Beaufort scale, I thought that it would make sense if the wind speed ranges in mph would also be based on the Beaufort scale to ensure uniformity and traceability to the same basis/standard.

Nevertheless, I noticed that the wind speed ranges in kts and mph in the Wikipedia templates and other Wikipedia articles were not based on the Beaufort scale, but were derived by converting the values from km/h and rounding them to the nearest whole number. This resulted to overlapping threshold values (e.g. 48 kts and 55 mph as both upper limit of TCWS #2 and lower limit of TCWS #3) and, of course, the ranges not following the Beaufort scale like the wind speed ranges in km/h, m/s and kts (as laid out by PAGASA). So now, I'm wondering how we can reconcile all of our edits so that the information regarding the TCWS system will be the same across all concerned Wikipedia articles and templates.

Thank you very much, and have a nice day everyone! —Nairb.Idi9 (talk) 13:36, 6 June 2023 (UTC)[reply]

I applied the convert template to this article yesterday in order to ensure that our conversions are consistant with other pages across the wiki, however, as you have pointed out this has caused a minor problem with our conversions not being consistant with PAGASA's conversions. My suspicion is that PAGASA's conversions are not correct but I need other editors opinons here.Jason Rees (talk) 14:34, 6 June 2023 (UTC)[reply]
