redfox Posted April 5, 2006 Posted April 5, 2006 I need to express blood pressure in terms of kPa. The conversion is 1kPa - 7.5mmHg, or .133 kPa - 1mmHg, but how would this be expressed? Just kPa subsituting mmHg, ie kPa/kPa?
hybrid04 Posted April 5, 2006 Posted April 5, 2006 Use dimensional analysis. Take your starting units plus some conversion factor. You'll have to excuse my lack of latex skillz. Just make sure units cancel. For example if you have 100mmHg. (100mmHg) (.133kPa/1mmHg) =13.33 kPa and vice versa. If you start with kPa you divide it by .133 istead of multiply to get the opposite. All you need is the converstion factor and make sure your units properly cancel.
swansont Posted April 5, 2006 Posted April 5, 2006 You mean for systolic and diastolic? That would seem fine.
redfox Posted April 6, 2006 Author Posted April 6, 2006 No, what I mean is would I simply convert the equations and express it in the same way blood pressure is expressed, or would it be written out in a different format? ie bp is written out 120/80. Substituted that would be 15.96/10.64, I'm just wondering if that's the correct format, 15.96/10.64, or should it be expressed differently ie 15.96kPa / 10.64kPa or do the two somehow combine...?
hybrid04 Posted April 7, 2006 Posted April 7, 2006 I dont see why it would make a difference. Your best guarentee would be to put the units on as to prevent any confusion id say, but im not really speaking from expertise. So just get xx mmHg/ xx mmHg and put in xx kPa/ xx kPa.
