The Units of Capacity • Capacity: It is the amount a container can hold. Within the customary system, the common units for measuring capacity are fluid ounces, cups, pints, quarts, and gallons. Examples: A standard cup of coffee. A can of coke is 12 fluid ounces. A gallon of milk. Fluid Ounce (fl.oz.) One fluid ounce is equal to 2 tablespoons. 1 fl oz = 2 tbsp. Gallon + + + A customary unit of capacity. One gallon is equal to 4 quarts. 1 gal = 4 qt Quart (qt.) 1tall glass of lemonade = 1 pint One quart is equal to 2 pints. 1 qt = 2 pt Pint (pt.) One pint ( approx. a tall glass of lemonade) is equal to 2 cups. 1 pt. = 2 cups Tablespoon (tbsp) One tablespoon is 3 teaspoon. 1 tbsp. = 3 tsp. Teaspoon (tsp.) Three teaspoon is one tablespoon. 3 tsp = 1 tbsp. Units of Length. • Length : It is a measure of the length of an object. The common units for measuring lenght in the customary system are inches, feet, yards, and miles. Examples: A ruler is a foot. There are 12 inches in a foot. A football field is measured in yards. The distance from here to Flagstaff is measured in miles. Inches • There are 12 inches in a foot. • 12 in. = 1 foot. • 1 ruler = 12 inches/1 foot Yards • There are 3 feet in a yard. • 3 ft. = 1 yd. • 36 in. = 1 yd. • Football/soccer fields are measured in yards. Miles • There are 1,760 yards in a mile • 1,760 yd. = 1 mi. • The distance from here to Flagstaff is measured in miles. Units of Weight. • Weight : It is a measure of the heaviness of an object. The common units for measuring weight in the customary system are ounces, pounds, and tons. Examples: A loaf of bread is a pound. A compact car weighs a ton. Pound (lb.) A pound is equal to 16 ounces. 1 lb. = 16 ounces. 1 pound of bread = One 16 ounce Jelly jar. Ounce (oz.): 16 ounce is one pound . 16 (oz.) = 1 lb. 16 ounce jar = 1 pound cake Ton (T) : One ton is equal to 2000 pounds. 1 T = 2000 lbs. A compact car weighs one ton or 2000 pounds. The Units of Time The common units for measuring time in the customary system are seconds, minutes, hours, days, weeks, month, and years. DAY One day is equal to 24 hours . 1 day = 24 hrs Hour (hr.) One hour is equal to 60 minutes. 1 hr. = 60 min. Minute(min) : One minute is equal to 60 seconds. 1 min = 60 sec. Second(sec): One second is equal to one sixtieth of a minute. 1 sec = 1/60 min. Week One week equals seven days. 1 week = 7 days Month : One month is one of the 12 parts into which a year is divided. Year: 1 year equals 365 days or 52 weeks or 12 months. Leap year A unit of time equal to 366 days. Decade : 1968 1978 1988 1998 2008 A unit of time equals 10 years. 1 decade = 10 years Measure of Time Digital Clock : Shows time with number. Hours are separated by a colon. Analog Clock : Shows time by pointing to numbers on a face Elapsed time : The amount of time between the beginning of an event or the end of an event. A music lesson started at 9:30 a.m and ended at 10 :25 a.m What is the elapsed time? Units of Temperature Degrees of Fahrenheit (F): A standard unit of temperature.
