in the metric system everything is related by a factor of 10! you go up by 10 and you can do down by 10!

ex:1 m=1000mm=100cm

remember what prefixes mean like deci,centi,milli,kilo

It relies upon on the gap. in case you’re speaking approximately your place, it may be in meters. Rain is measured in millimeters (mm), while snow, on account that’s thicker, is in centimeters (cm.). As for traveling, distance is measured in kilometers (km.). those are the 4 maximum used lengths. in case you’re in a u . s . a . that makes use of the metric device, and there has been a bad rainstorm, you will pay attention that x quantity of mm. of rain has fallen. Now, in case you’re a smoker (and we are going to pass with Benson and Hedges because of the fact i think of that they’ve been the 1st), you are able to extraordinarily plenty discern it out. If 20 mm. of rain got here down, a B & H cigarette is one hundred mm. long. meaning that the entire quantity of rain that got here down grow to be a million/5 of the size of the cigarette. With snow, 20 cm. could be 2 cigarettes, because of the fact 20 cm. is 200 mm. As somebody else has pronounced, that’s based on the huge style 10: 10 mm. = a million cm. 10 cm. = 1dm. (decimeter) 10 dm. = a million m. (meter) 10 m. = 1Dm (Decameter) 10 Dm. = a million hm. (hectameter) 10 hm. = a million km. the common element related to the metric device is that the comparable holds actual for drinks. Liters are measured the comparable way, via putting the right prefix formerly the be conscious “liter”. Weights shop on with the comparable rule of thumb–milligrams, grams, kilograms, etc. this is the area the place you attempt to transform them which you run into worry. this is now and back complicated to bear in ideas the ratios. i comprehend that this could properly be a protracted explanation, yet i’m hoping that it helped fairly.
