You can calculate joules from watts and seconds, but you can't convert watts to joules since watt and joule units represent different quantities. Watts-per-kilo (W/kg) is a rider’s power output for a given effort divided by their weight. On a smooth, flat road, cyclists with a greater power number will almost always go faster. Note that rounding errors may occur, so always check the results. SAR For Cell phones – … I upped my volume by 33% this year to 400/week with every 4th week at a lower volume but same intensity, and I’m 49, 68 kg and about 4.8 watts/kg. By comparison, one candidate for the next generation of batteries--fuel cell batteries--offers charging times of a few seconds and 1,000 watt hours per kilogram. It is expressed as watts of cycling power produced per kilogram of body weight, abbreviated as W/kg. Watts per Kilogram, unlike many of the other metrics cyclists track, is relatively straightforward to improve. Power units represent power physics, which is the rate at which energy is used-up, either transformed or transferred from its source to … We would like to show you a description here but the site won’t allow us. Specific absorption rate (SAR) is a measure of the rate at which energy is absorbed per unit mass by a human body when exposed to a radio frequency (RF) electromagnetic field.It can also refer to absorption of other forms of energy by tissue, including ultrasound. You're confused. If not, you can calculate it as Volts x amp hours (Ah). The rate of energy release gives power. • Use current calculator (page) to convert Radiation from Sievert per second to Watt per Kg. Body weight will always play a role and normally play the biggest role in the mountains (X closer to 1). Watts per kilogram^X would possible be a better predictor of performance because there are no events that can be predicted accurately by watts or watts per kilogram only. Both Sievert per second and Watt per Kg are Radiation measurement units. It allows you to climb hills faster while at the same time expending less energy. We assume you are converting between watt and kilogram-force meter/second. Once the riders hit that final ascent Pogačar rode at 474 watts for 4:29, or 7.18w/kg, before a 3:28 period at an average of 420 watts or 6.36w/kg. The rem/second [rem/s] to watt/kilogram [W/kg] conversion table and conversion steps are also listed. You are relatively light though so a bit of work on your ftp and you should do fine. Watts per kilogram is a dynamic metric that can be readily improved once you understand exactly what it is, and why it’s important to your goals as a cyclist. The rule relates to how many Watts (W) of power are needed per pound (lb) of airplane, and the approximate values range from 50W to 200+W. The common value is between 1 and 7, whereas 1 is a value of physically weakened or ill people. So take a breath relax and listen. I realize this question is multifactorial and contingent on swim and run capabilities as well; however, what do typical … CG Bob. This value is measured at cycling or with a bicycle ergometer, to compare the power of persons with different weights. Dunbar’s heart rate was higher than some … More of a 'rule of thumb' than a hard and fast rule, the Watts per pound rule is one that lets you determine the power output needed for your electric rc airplane, to give it the performance that you desire.
