LENGTH
Mile
A mile is equivalent to 1609.344
m.
1 mile = 1.6 km
Miles are often used to measure long distances where we
would use kilometers in Spain.
For instance, distance between cities is measured in
miles.
Car speed is also measured in miles per hour (mph).
LENGTH
Yard
LENGTH
Yard
A yard (abbreviation: yd) is the basic unit of
length used in the UK and the USA.
One yard is equal to 0.9144 meters.
One meter is equal to 1.094 yards.
“He missed the shot by less than a yard”
“My house is only a couple hundred yards
away”
LENGTH
Feet
LENGTH
Feet
A foot (abbreviation: ft) is defined as a third
of a yard.
1 yard = 3 feet
1 foot = 0.9144 m : 3 = 0.3048 m = 30.48
cm
Feet are divided in inches. There are
twelve inches in one foot.
1 foot = 12 inches
1 yard = 36 inches
1 inch = 2.54 cm

Exercise 1
What is the speed limit in
kilometers per hour?
What is the actual speed of the
car?
LENGTH
Exercise 2
We see this sign at one side of
the road.
What does it mean?
LENGTH
Exercise 3
Pau Gasol and Ricky Rubio are two
Spanish basketball players.
Pau is a very tall man. He is 7 ft. tall.
Ricky is only 6 ft. 4 in. tall.
Therefore, Pau is 8 inches taller than
Ricky.
How much is that in meters?
How tall are you?
LENGTH
Exercise 3: How tall are you?
I am 165 cm
tall
165 : 30 = 5
5 feet
remainder =15
15 : 2.5 = 6
inches
I am 5 ft. 6 in. tall
MASS
MASS
Pound
A pound (abb.: lb) is an unit of weight with a
long history.
The word pound comes from the Latin word
pendere, meaning “to weigh”. The Latin
word libra means balance and it also
describes a Roman unit of mass similar to a
pound. This is the origin of the abbreviation
“lb” for the pound.
One pound is equal to exactly 453.59237
grams. We round it by 453.6 g.
Sometimes, we can estimate 1 lb = ½ kg
MASS
Ounce
There are sixteen ounces (oz.) in one
pound.
16 oz. = 1 lb
1 oz. = 453.6 : 16 = 28.35 g
Ounces are frequently used in grocery
stores and supermarkets.
MASS
Stone
A stone (st) is an unit of weight and
mass, equal to 14 pounds.
1 st = 14 lb = 6.35 kg
It is used to express human body
weight (only in the UK and Ireland).
Example: John weighs 11 st 4 lb. John
weighs 158 pounds. John weighs 71.7
kg.
MASS
Exercise 4
We want to buy some
fruit in the supermarket.
The price of one pound
is $2.50
What is the price of 1
kg?
We have bought 2 lb 6
oz. How much do we
have to pay?
MASS
Exercise 5
How many stones are in 112
pounds?
How many ounces are there in 3
lb?
Complete:
½ lb = ___ ounces
¼ lb = ___ ounces
VOLUME
VOLUME
Gallon
A gallon is an unit of volume. Its exact
value depends on wether we are in
the UK or the USA.
1 US gallon = 3.785 litres
1 UK gallon = 4.546 litres.
VOLUME
16 US fl.oz.= 1 pint
1 pint = ½ quart
1 US fl.oz. = 29.6 ml 1 pint = 473 ml
1 quart = ¼
gallon
1 quart = 946 ml
VOLUME
Exercise 6
In the picture you can see the
price of one gallon of gas.
1 gallon = $ 3.47
In Spain, one liter of gas costs
1.42 €
Is gas more expensive or cheaper
in the US? How much?
VOLUME
Exercise 7
In the picture you can see the
average mileage of an US car.
1 gallon = 40.2 miles
In Europe we measure the mileage
the other way around:
100 km = 4.5 liters
Can you convert that mileage into
liters per 100 km?
VOLUME
VOLUME
AREA
Acre
The acre is a unit of area.
One acre is equal to 4.84 squared
yards or 43.56 squared feet.
One acre is, more or less, a football
field.
1 acre = 4047 m2
1 acre = 0.4047 ha
TEMPERATURE
TEMPERATURE
Fahrenheit
Temperature can be measured in
Fahrenheit degrees. For
example, the weather forecast
can predict a maximum
temperature of 85 ºF in a nice
spring day.
0º C = 32 ºF 100 ºC = 212 ºF.
Celsius (C) Fahrenheit (F):
F = 1.8 · C + 32
Fahrenheit (F) Celsius (C)
C= (F – 32) / 1.8
