Temperatures are most often reported in Fahrenheit, and occasionally also in Celsius. To convert Fahrenheit to Celsius, subtract 32 and multiply the result by 5/9. The following table lists a few common temperatures:
|212||100||boiling point of water|
|98.6||37||normal body temperature|
|86||30||very hot summer day|
|68||20||mild spring day|
|50||10||warm winter day|
|32||0||freezing point of water|
|20||-7||very cold winter day|
Climate varies considerably across the USA. You will probably need an umbrella, even in Las Vegas or Los Angeles. In the northern cities, such as Boston, Chicago, Pittsburgh, New York, Seattle, Washington, Denver, and Minneapolis you will need cold weather and snow gear. In the southern states, such as California and Florida, summers may be very hot and the winters mild. Depending on the part of the country, temperatures during the summer will run from the 70s through the 90s.
No matter where you are in the US, you will probably need a sweater or jacket for part of the year. If you will be living in an area that gets snow, you will need a good winter coat, boots, and gloves. If the coat does not include a hood, you will need a hat that covers your ears. But all this can wait until after you arrive in the US. Clothing is relatively inexpensive in the US, and it may be easier to find appropriate clothing at your destination. Wait until you arrive, and watch what the natives wear.
The USA has four main time zones: Pacific Standard Time (PST), Mountain Standard Time (MST), Central Standard Time (CST), and Eastern Standard Time (EST). When it is 9:00 am in California (PST) it is 10:00 am in Denver (MST), 11:00 am in Chicago (CST), and 12:00 noon in New York (EST). Alaska is one hour earlier than California, and Hawaii is two hours earlier. Puerto Rico is in the Atlantic Standard Time zone, one hour after New York. Guam is fourteen hours after New York. If you are on the east coast of the USA and calling someone on the west coast, they are probably still asleep at 9:00 am your time. If you are on the west coast and calling someone on the east coast, they are probably eating dinner at 4:00 pm your time.
The following table lists the states that occur in each time zone. States that span two time zones are italicized.
|Eastern||Connecticut, Delaware, District of Columbia, Florida, Georgia, Indiana, Kentucky, Maine, Maryland, Massachusetts, Michigan, New Hampshire, New Jersey, New York, North Carolina, Ohio, Pennsylvania, Rhode Island, South Carolina, Tennessee, Vermont, Virginia, West Virginia|
|Central||Alabama, Arkansas, Florida, Illinois, Indiana, Iowa, Kansas, Kentucky, Louisiana, Michigan, Minnesota, Mississippi, Missouri, Nebraska, North Dakota, Oklahoma, South Dakota, Tennessee, Texas, Wisconsin|
|Mountain||Arizona, Colorado, Idaho, Kansas, Montana, Nebraska, New Mexico, North Dakota, Oregon, South Dakota, Texas, Utah, Wyoming|
|Pacific||California, Idaho, Nevada, Oregon, Washington|
The following table lists the number of hours ahead or behind Eastern Standard Time for cities around the world. Add the number to Eastern Standard Time to arrive at the time in the named city, or subtract it from the time in the named city to obtain Eastern Standard Time.
|City||Time Delta||City||Time Delta||City||Time Delta|
|Ho Chi Minh City||+13||Hong Kong||+13||Istanbul||+7|
|Quebec||+0||Rio de Janeiro||+2||Riyadh||+8|
|Rome||+6||St. Petersburg||+8||San Juan||+1|
|Zurich||+6|| || || || |
During Daylight Savings Time clocks are set forward one hour. It begins on the first Sunday in April and ends on the last Sunday in October. The mnemonic “Spring Forward, Fall Back” will help you remember how to set your clocks. Not every state conforms to Daylight Savings Time; for example, Indiana and Guam never change their clocks.
