Systems of Measurement (Maths)

Question 1

Roman Numerals Seven Symbols

Answer 1

ss 1/2

I 1

V 5

X 10

L 50

C 100

D 500

M 1000

Question 2

Fahrenheit

Answer 2

temperature scale based on measurement system proposed in 1724 by German physicist Gabriel Fahrenheit

• water freezes at 32ºF
• water boils at 212ºF
• 180 degrees of separation between the two points

*at sea level and standard atmospheric pressure

Question 3

Celsius

Answer 3

scale for measurement of temperature developed by Swedish astronomer Andres Celcius in 1742

• water freezes at 0ºC
• water boils at 100ºC
• used to be called centigrade

*at sea level and standard atmospheric pressure

Question 4

Celcius to Farenheit Relationships

Answer 4

• Farenheit scale runs from 32 - 212 with a 180 degree separation
• Celcius runs from 0 - 100, a 100 degree separation
• Every 9 degrees of Farenheit = 5 degrees of Celcius (180/100 or 1.80)

Question 5

Solve for ºF

Answer 5

ºF = (1.80 x ºC) + 32º

Question 6

Solve for ºC

Answer 6

(ºF - 32º)/1.80 = ºC

Question 7

Household Measure Equivalents

Answer 7

3 tsp = 1 tbsp

2 tbsp = 1 fl oz

8 fl oz = 1 c

2 c = 1 pt

2 pt = 1 qt

4 qt = 1 gal

1 lb = 16 oz

Question 8

Common metric prefixes and units

Answer 8

kilo (k) = 1000 (one thousand)

deci (d) = 1/10 or 0.1 (one tenth)

centi (c) = 1/100 or 0.01 (one hundredth)

milli (m) = 1/1000 or 0.001 (one thousandth)

micro (mc or µ) 1/1,000,000 or 0.000001 (one millionth)

Question 9

kg

Answer 9

kilogram

Question 10

dL

Answer 10

deciliter

Question 11

cm

Answer 11

centimeter

Question 12

mL or ml

Answer 12

milliliter

Question 13

mcg

Answer 13

microgram

Question 14

Household/Metric Conversions

Answer 14

1 tsp = 5 mL

1 tbsp = 15 mL

1 fl oz = 30 mL

1 c = 240 mL

1 pt = 480 mL

1 qt = 960 mL

1 gal = 3840 mL

1 oz = 30 g

1 lb = 454 g

2.2 lbs = 1 kg
