The rest of the World has adopted SI, not just the Eu. And the USA recently lost a multi-million [unit of currency] spacecraft through refusing to follow the rest of the world. 'JNT On 7 Januar
So, according to this, we should also ban volts, amperes, henries, coulombs, etc etc And use "jars" for capacity, according to the ancient UK unit, intead of farads Jean-Louis F6AGR
It must have been in their April number, as the "conversion ratio" from c/s to Hz is 1. The introduction of the SI system in general was controversial in some countries that not ready to give up loc

Dear All, I think the real reason for changing from cycles/second is that the units describe the dimensions of the quantity. Dimensions in physics are relatively few things: mass, length, time etc. C
No they aren't. They are related simply to NUMBER of OCCURRENCE. The quantification of "FREQUENCY of OCCURRENCE" requires a time reference during which the given "NUMBER of OCCURRENCES" happen. Which
Dear Colleagues, That whole discussion is a nice proof for the importance of a principle what is called "Freedom of Opinion". And furthermore how necessary dissenting opinions are for generating crea
Pete, I can't remember it being "WileyWerld" but there was also a nomograph for that conversion which required the use of C (Plancke's) in the conversion formula when used on the first day of the fou
Yes Mal, and Farad is another "someones name". CENTIMETRES is the proper unit for capacitance which can be measured with a ruler and it is easy to scale to other units of length, for example yards, i
those who prefer to use units that were decommissioned in 1960 (when the SI system was introduced) should at least do it correct : "cycles per second", just "cycles" is meaningless. So we also have
Tony In the electronic context. There are CYCLES, KILOCYCLES and MEGACYCLES all related to FREQUENCY of OCCURENCE and can be observed on a 'Scope for example but what does a HERTZ look like. Hertz is
Maybe Mal. But Kilocycles etc are of absolutely no use unless referenced against time .. eg cycles per second/hour/ day/ year, HERTZ automatically includes per second as an SI unit. Tony, On 07/01/20
Gentlemen and Mal After careful study of Mal's comments of late it is clear he fancy's a unit being named after him. How could the world's greatest CW operator not be so recognized? Fortunately for M
I fully support the use of UTC as the standard for grabbers, mine timestamps that way. Mal, CYCLES, KILOCYCLES and MEGACYCLES ARE TOTALLY MEANINGLESS in the way you have offered them. Hertz is at wor
