أما في حالة التحويل من وحدة صغيرة إلى وحدة كبيرة نضرب في معامل بأس سالب

20. Which of the following is the smallest
distance?
(a) 21 m
(b) 2.1 x 102 cm
(c) 21 mm
(d) 2.1 x 104 pm
Put all of them in the same unit
→ 21m
→ 2.1m
→ m
→ 2.1 x 10-8 m

21. Measurement
1- mass is a measure of the quantity of matter in an object
SI unit of mass is the kilogram (kg)
1 kg = 1000 g = 1 x 103 g
weight - force that gravity exerts on an object

22. weight = c x mass A 1 kg bar will weigh
The Mass of an object doesn't change when an object's location changes. Weight, on the other hand does change with location.
weight = c x mass
on earth, c = 1.0
on moon, c ~ 0.1
A 1 kg bar will weigh
1 kg on earth
0.1 kg on moon

23. 2- Volume – SI derived unit for volume is cubic meter (m3)
Volume = width × length × height
= m × m × m = m3
1 dm3 = (1 x 10-1 m)3 = 1 x 10-3 m3
1 cm3 = (1 x 10-2 m)3 = 1 x 10-6 m3

24. The relationship between (L), (mL) and metric system
1 L = 1000 mL = 1000 cm3
1 L = 1 dm3
1 mL = 1 cm3

25. Examples Convert the followings to m3 2.5x104 cm3 1.20x 10-3 dm3
Convert the followings to mL
800 L
3.09 cm3

26. Examples
The diameter of an atom is approximately 1  10-7 mm. What is this diameter when expressed in nanometers? 
A. 1  nm
B. 1  nm
C. 1  10-9 nm
D. 1  10-1 nm
How many cubic centimeters are there in exactly one cubic meter? 
A. 1  10-6 cm3
B. 1  10-3 cm3
C. 1  10-2 cm3
D. 1  106 cm3

27. m d v 3- Density – SI derived unit for density is kg/m3 mass m
volume
d = m V d v
1 g/cm3 = 1 g/mL = 1000 kg/m3
1 g/mL = 1×10-3 g/L

28. A piece of platinum metal with a density of 21
A piece of platinum metal with a density of 21.5 g/cm3 has a volume of 4.49 cm3. What is its mass?
d = m V

29. Common unit of volume is liter (L) and milliliter (mL)
1 L = 1000 mL = 1000 cm3 = 1 dm3
The relationship between (L), (mL) and metric system
1 mL = 1 cm3
1 L = 1 dm3

30. Example

33. 4-Temperature Scales
There are three temperature scales, their units are:
1. Degrees Celsius 0C
2. Degrees Fahrenheit 0F
3. Kelvin K
Kelvin is the SI Base Unit of Temperature

34. K = 0C
273 K = 0 0C
373 K = 100 0C

39. Example 1.3: (a) Convert 224 0C → 0F? °F = [(9 /5 ) × °C ] + 32
[°F = (9 /5 ) × 224 °C] + 32 = 435 0F
(b) Convert F → 0C ?
°C = (5 /9 ) (°F - 32 )
°C = (5 /9 ) ( ) = C
(c) Convert C → K ?
° K = °C = K

40. Temperature Units Conversion
K → °C or °C → K
K = °C
°C = K
°F → °C or °C → °F
°F = [ (9/5) × °C] + 32
°C = (5/9) (°F - 32)
No relatationship between
K → °F or °F → K
Thus: K → 0C → 0F or 0F → 0C → K
