Conversions 3 Base Words 6 Prefixes Values Metric Ladders Conversions Meter, Gram, Liter – Tells you what you are measuring: distance, mass, or volume kilo, hecto, deka, deci, centi, milli K – 1000, h – 100, dk – 10, base -1, d.1, c -.01, m -.001 km, hm, dkm, m, dm, cm, mm - distance kL, hL, dkL, L, dL, cL, mL - volume kg, hg, dkh, g, dg, cg, mg - mass We can convert from one prefix to another by moving the decimal point – Find Start and End points – Count how many spaces you need to move to get from start point to end point – Decide if you need to move right or left – Move decimal
3
Example 2.34 km to m To get from k to m is 3 spaces Moved to the right New number is 2340 m You must add zeroes if necessary to hold value
4
Perimeter, Area Perimeter Area The total distance around the outside of an object – Use distance (mm,cm,m) – S + S + S + S The total surface space in a two dimensional figure – Use distance (mm,cm,m) – S x S – Answer is always squared
