Part 25 (2/2)

________________________________________ ___________________ Milli- = one thousandth 1-1000 .001 Centi- = one hundredth 1-100 .01 Meter for length.

Deci- = one tenth 1-10 .1 Unit = one 1. Gram for ma.s.s.

Deka- = ten 10-1 10. Hecto- = one hundred 100-1 100. Liter for capacity.

Kilo- = one thousand 1000-1 1000. ============================================================

The metric terms are formed by combining the words ”Meter,” ”Gram” and ”Liter” with the six numerical prefixes.

LENGTH

10 milli-meters mm = 1 centi-meter c m

10 centi-meters = 1 deci-meter d m

10 deci-meters = 1 meter (about 40 inches) m

10 meters = 1 deka-meter d k m

10 deka-meters = 1 hecto-meter h m

10 hecto-meters = 1 kilo-meter (about 5/8 mile) k m

Ma.s.s.

10 milli-grams. m g = 1 centi-gram c g 10 centi-grams = 1 deci-gram d g 10 deci-grams = 1 gram (about 15 grains) g 10 grams = 1 deka-gram d k g 10 Deka-grams = 1 hecto-gram h g 10 hecto-grams = 1 kilo-gram (about 2 pounds) k g

CAPACITY.

10 milli-liters. m l = 1 centi-liter c l 10 centi-liters = 1 deci-liter d l 10 deci-liters = 1 liter (about 1 quart) l 10 liters = 1 deka-liter d k l 10 deka-liters = 1 hecto-liter (about a barrel) h l 10 hecto-liters = 1 kilo-liter k l

The square and cubic units are the squares and cubes of the linear units.

The ordinary unit of land area is the Hectare (about 2-1/2 acres).
