A paragraph could very well be one sentence, but it could just as easily be a long 20 sentence paragraph. It's usually thought of as being a complete separate thought and containing as many sentences are needed before you reach a natural breaking point to move on to the next paragraph. Hope that helped.
Centi-means one-hundredth, so 1metre = 100 centimeters, therefore 1 decameter = 10 x (100 centimeters) = 1000 centimeters. Hecto-means one hundred, therefore 1 hectometer = 100 meters = 10 decameters. Kilo-means one thousand, of course, so 1 kilometer = 1000 meters, and since 1 hectometer = 100 meters, 1 kilometer = 10 hectometers.
Meter to Hectometer Conversion Example. 1  Task: Convert 750 meters to hectometers (show work) Formula: m Ã· 100 = hm Calculations: 750 m Ã· 100 = 7.5 hm Result: 750 m is equal to 7.5 hm. 2  Task: Convert 25 hectometers to meters (show work) Formula: hm x 100 = m Calculations: 25 hm x 100 = 2,500 m Result: 25 hm is equal to 2,500 m.
