1. This document provides information on unit conversions for mass, volume, length, and temperature using conversion charts and formulas. 2. Examples are given to demonstrate how to use the conversion charts to change between units like mg, g, km, m, mL, L, °C, °F, and K. 3. Key temperature conversion formulas are outlined to change between Celsius, Fahrenheit, and Kelvin scales, and notable temperature values are listed.

1. Conversion

2. Base Unit Abbrev. Mass gram g Volume liter l or L Length meter m Temp. Celsius ° C

3. To convert mass/volume/length, use the conversion chart. kilo- k hecto- h deca- da deci- d centi- c milli- m Meters Liters Grams

4. 1. mg = 2. decaliter = 3. kilometer = 4. dl = 5. m = milligram dal km deciliter meter mm = millimeter

5. How to use the conversion chart. 1. Find your starting point 2. Find your ending point 3. Find the direction…R or L 4. Count the # of steps from the starting to ending point. 5. Move the decimal in the direction and # of steps.

6. Ex: 3 mg = ______ g k h da d c m 1. Start Pt. 2. End Pt. 3. Left 4. Count # of steps 1. 2. 3. 5. 3. 0 0 . 1. 2. 3. so…3 mg = .003 g m l g

7. Ex: 1. 4.6 km = m 2. .009 dg = dag 3. 2 kl = cl 4. 8.53 g = hg 5. 17 m = mm 200000 .00009 4600 .0853 17000

8. Temperature Conversion 3 Ways to measure temperature 1. °C 2. °F 3. K- Kelvin

9. To convert to °F ___ °C X 1.8 + 32 Ex: 100 °C X 1.8 + 32 = 212 °F To convert to °C ___ °F - 32 / 1.8 Ex: 32 °F -32 / 1.8 = 0 °C

10. Kelvin (K)- unit of temperature. Kelvin scale – a temperature scale where absolute zero is 0 K. At 0K, is the temperature where there is no thermal energy. To find K ___ °C + 273

11. Ex: 20 °C = ____K 20 °C + 273 = 293 K Absolute zero (0K) is extremely cold. Coldest on Earth = -89°C or -128°F or 184K Closest 9/03 = MIT 4.5 X 10-10 Pluto = -233°C or -387°F or 40 K Neptune = -235°C or -391°F or 38 K

12. Boiling and Freezing Points of Water The Boiling points of water are 212°F, 100°C and 373 K. The Freezing points of water are 32°F, 0°C and 273 K.

13. 36 °C = 62 °F = 98.6 °F = -10 °C = 50 °C = 45 °F = 500 K = 60 °F = 96.8 or 97 °F 16.6 or 17 °C 37 °C 14 °F 323 K 7.2 or 7 °C 227 °C 228.5 or 289 K
