Practice, ALOT. It never hurts to practice,

Ideas:
Go around your kitchen and measure some objects (for mass).

I just take whatever's next to me and weigh it. I have a pretty long list going right now...the more you measure and weigh, the better prepared you will be.

Oh, and just a question, we're not allowed to touch ANYTHING during the competition right? This is my first year doing Metric.

Thanks

During the estimating part of the competition, you may heft (lift up and feel the weight) things for which you are estimating mass or weight. That's because you cannot always tell what you are dealing with just by looking. If you are asked to estimate the mass of a box, you cannot tell by looking if the box contains air, bricks, or something in between. So, you can heft it and feel how heavy it is in your hands.

Of course, during the measurement part, you can handle the objects.

Even after going through your tips hscmom, I am still kind of stuck on how to prepare for competition. At competition it seems to be much more difficult than simple estimation and measurement. How do I prepare for things like: A disc with multiple holes, of different sizes, and find the area of one of the circles? Or estimate the temperature of a container of water in a hot room with huge amounts of people inside? It seems that even if you prepare and practice a lot, it's almost impossible to know how you will do at competition. Any help?

At competition it really is impossible to know what they are going to throw at you. Preparing for competition can be stressful.

I'll use your example of a disc with holes in it.

What I would do is, practice.

How to measure the disc:
I would first find the area of the disc. (let's say 500 cm squared)
Then I would look to see if the holes were all the same size, if the were I would measure a hole and get the are of the hole (19 cm squared)
Then I would count the holes (let's say there are 12 holes)
Then I would multiply the #of holes to the area of the hole (19 times 12=228)
Now, I would subtract the area of the disc (600) , by the area taken up by the holes (228). So in the case, the answer would be 372.

NOW, if the holes were not the same size, I would measure the area of the holes (write down the areas on the back of my paper) and then subtract the added up area of the holes by the area of the disc.


NOW FOR THE WATER:
Just get use to the temperature of water (in celsius of course). Be ready to convert celsius to kelvin (celsuis times 274.15= kelvin). Remember, Kelvin is not measured in degrees.


I hope I helped. Also the advice hscmom gave helps a lot.

plus 273.15, not times

Honestly, I would remember to use VERY unused measurements... because you'll use them. Also, try to be better with the smaller units, so if you convert it up you're closer to the margin of error than say if you converted down from meters to centimeters and the such.

The "very unused" you want to focus on are metric units! No hogsheads or slugs or whatever.

So I went to an invitationals, and the 5 metric conversion problems were more complicated than meters, cm, mm, km, etc. So my question is, what should we expect for regionals in our conversions? Just the simple khdudcm, or terra, giga and that stuff/periods(in frequency),etc.?

^ True But the Imperial system is also used.

Honestly, I think invitationals are run better than regionals (at least for how it is in Division B). Thus, invitationals will be a bit harder. However, be sure to expect even more complex measurements beyond km, cm, and mm. However, it's usually the smaller measurements. Unless they put a proportion or something I don't think they'd be able to ask for gigameters or something . You never know, though. Just think about it though. This is regionals. If it was nationals, they might get random things you've NEVER seen before, but with regionals you might be able to find everything at your house.
