The document discusses two main measurement systems - the English (British) system and the International System of Units (SI or metric system). It provides the base units for mass, volume, distance, and temperature in each system. It also explains the prefix multipliers used in the SI system, from giga to nano, and provides examples of converting within and between the two systems using conversion factors.

1. Measurement Systems

2. English (British) System
–Variables & unit
•Mass – pound (lb)
•Volume – gallon (gal)
•Distance – feet (ft), inch (in), yard
(yd)
•Temperature – Fahrenheit (oF)

3. SI (metric) – International System of Units
–Variables & unit
•Mass – gram (g)
•Volume – liter (L)
•Distance – meter (m)
•Temperature – Celsius (oC) or Kelvin (K)
•Time – second (s)

6. • Multiples of 10
• Multiply or divide by 10 to change #
• Every multiple has a prefix

7. –other prefixes:
• Giga (G)- 1,000,000,000
• Mega (M)- 1,000,000
• Micro(m)- 0.000 001
• Nano (n)- 0.000 000 001
–Acronym to remember order of prefixes:
• King Henry Died By Drinking Chocolate Milk

8. How to Convert
– Determine how far and what direction the
decimal will move
– Then convert!
• Ex) 0.01 cm = ___________ m
5 m = ______________ mm
5 km = ____________ m
0.4 mm = ___________ km

9. SI to English Conversions:
– To convert between SI and English you need the
conversion factor
– Setup conversion as a ratio to cancel out units

10. • Ex) 50 lb = ______kg
99 cm = ______ in
7 km = ______ mi
