What do we measure and what do we measure it in?
International System of Units (SI) System used by all scientists around the world to share precise data in a format that is understood by all What do we measure and what do we measure it in? Length – measured in meters (m) Volume (how much space something takes up) – measured in - Liters (if liquid) (L) Cubic meter units (if solid) m3

H DA D C M Scale based on units of 10
K 1000 H 100 DA 10 10 times smaller each step D 0.1 C 0.01 M 0.001 10 times larger each step King Henry Died By Drinking Chocolate Milk

How many jumps does it take?
Ladder Method- Length 1 2 3 KILO 1000 Units HECTO 100 Units DEKA 10 Units 10 times smaller each step km DECI 0.1 Unit hm m CENTI 0.01 Unit dam MILLI Unit dm cm 10 times larger each step mm How do you use the “ladder” method? 1st – Determine your starting point. 2nd – Count the “jumps” to your ending point. 3rd – Move the decimal the same number of jumps in the same direction. 4 km = _________ m Starting Point Ending Point How many jumps does it take? 4. 1 __. 2 __. 3 __. = 4000 m

Ladder Method- Length KILO 1000 Units HECTO 100 Units DEKA 10 Units
10 times smaller each step km DECI 0.1 Unit hm m CENTI 0.01 Unit dam MILLI Unit dm cm 10 times larger each step mm 700,000 0.04 hm = _________ cm 400 70 km = _________ dm 0.5004 0.720 5004 cm = _________ hm 720 mm = _________ m

Conversion Practice k h da m L d c m
Try these conversions using the ladder method. 1000 km = _______ m 1 L = _______ mL 160 dam = _______ mm 14 km = _______ cm 109 cm = _______ mm 250 L = _______ ml 1,000,000 1,000 1,600,000 1,400,000 1,090 250,000
