Only if it applies to fluid volume. If it applies to volume of a solid, then it is traditional to use cubic centimeters, or even m^3. The latter is a heck of a big volume, and sounds almost silly, but it is increasingly used. For example, in the latest Ferroxcube ferrite core catalogue, specific v

Yep, cubic meters, of course. Don't forget to separate the value from the unit: 15 m3. Folks often omit the space between the 5 and the m. ANSI will punish! Chuck Mullett richwo...@tycoint.com wrote: > Nevermind. I found the answer to be cubic meters. > > > -Original Message- > > Fr

I cannot say if it is "acceptable", because I am not sure what your particular criteria for "acceptability" is. But I can say that there is no problem technically. In the company I previously worked for, we designed and made telco "rectifiers" (basically they are honking big 48V battery chargers

Assuming the sensed current in the coil is reasonably sinusoidal, skin depth at 100KHZ is about half the diameter of AWG 28, (if the winding is only one layer thick). This means that the entire wire cross sectional area will be carrying current. This was my reason for suggestion that particular wir

I believe the SI unit for volume is the cubic metre. A litre is 1/1000 of a cubic metre and not strictly speaking an SI unit. I wouldn't try asking for one thousandth of a cubic metre of engine oil at a service station though Chris Colgan Compliance Engineer TAG McLaren Audio Ltd The Summit
