Using (1) and (2), F = [MLT−2] This is the dimension of force. 1 kW-hr x 1000 w/kW x 3600 sec/hour = 3600000 watt-seconds = 3600000 joules. EXAMPLE 1 If you had a sample of a substance with a mass of 0.0034 grams, and you wanted to express that mass in mg, you could use the following dimensional analysis. 1 joule to erg = 10000000 erg. 2nd Use of Dimensional Equations To Derive Relationship Between Physical Quantities. No, we are in a jungle and find our way by trial and error, building our road behind us as we proceed.' Ratios, sometimes called conversion factors, are fractions that denote the correlation between the given unit and the desired unit. Dimensional analysis is based on the principle that two quantities having the same dimensions can only be compared with one another. Class-11-science » Physics. Select the current unit in the left column, the desired unit in the right column, and enter a value in the left column to generate the resulting conversion. convert 1 joule j into 39 erg 39 by using dimensional analysis - Physics - TopperLearning.com | omho8m22. 1 joule is equal to 10000000 erg.
