He meant the same unit, not different units. 3x/90x= 0.03333, or about 3%. X here can be any unit, be it MT, kg or m.
Can't say much about the rest. If it means anything, for most of my time in Engineering we only used kilograms. A tonne would have been 10^3 kg. The SI symbol for tonne is t, not MT, lower case letter not upper-case. I'm not familiar with the standard abbreviations for barbaric "English Units" are, but according to wikipedia it's simply "ton". I doubt MT is a proper way to write any unit. |

Ugh, I'm sorry, I probably shouldn't do this, but I figured to just give it a try. It's a question for my college paper.
Suppose 3 sets of data: g0,g1,g2. They represent measurements from the same positions, but from different heights (with irregular interval, h1-h0 =/= h2-h1). How do I derive a single gradient value using all 3 points simultaneously? That is, I'm not allowed to compute the gradient between g0 & g1, then g0 & g2, then averaging the two. I'd appreciate it if someone can point me to a paper on some methods or applications. I'm currently exploring finite difference, but have yet to see how to make it work.

However, I'm assuming each of those sets only has a single point. As a matter of interest what course is this for, and what year is the course for? That'll give me an idea of how complicated the solution needs to be. There are better (though more complex) methods to analyze data then what I wrote above, but they're advanced. I'm happy to explain anything that you need more clarification for. Also, I recently graduated from Mech Engineering, though after some months of idleness, I don't remember everything perfectly. |

So I have this problem.
I don't know what's worse, the actual problem or the fact that I don't know exactly what this problem is. In light of that, I'll just list some symptoms. - 'some' images do not load - Youtube videos 'sometimes' error out - 'some' sites just don't want to load Now, I'm pretty sure I'm connected to the net here.

I can name one: megatesla (tesla being the unit for magnetic field strength)

And yes, I heartily agree that barbaric 'English' units are an utter pain in the ass and its hard for me to take engineering seriously that clings to them. Furlongs per fortnight, tally ho!

If you means metric system, then it was opposite here with all those inches, feet, pounds and the like. @_@ I thought it was non-scientific units until read a hydraulic engineering textbook with these kind of units conversion... Not really fond of that book as you all may guess

I'd say it's still 2 in Japan. They aren't about to change their pricing model.
As for the west, well if it's anything, all of High School of the Dead is on one Blu Ray |

I'm having some mouth pain, which is vague since I can't exactly pinpoint 'where' the pain is.
The most accurate description I can give is that it's on the wall of my mouth opposite the last molar I can feel. Yeah, not on the tooth but on the wall facing it. What's going on? As far as I know Wisdom Teeth don't grow on the walls of your mouth.
