Units conversion examples
Problem 1. Acceleration
Gravity acceleration at the Earth surface is 9.81
How much is this in
1 ft = 0.3048 m (see, for example, the units converter under this topic
, or any appropriate handbook, textbook, or the Internet web-site).
So, 1 m = 1/0.3048 ft = 3.2808 ft = 12*3.2808 in = 39.37 in.
= 9.81 * 3.2808
Further, because 1 ft = 12 in, we have
= 32.19 *12
. Gravity acceleration at the Earth surface is 9.81
, or 32.19
, or 386.2
Problem 2. Speed
Car A makes 100 miles per hour, car B makes 120 kilometers per hour.
Which car is moving with larger speed?
To compare speed of these two cars, let's convert the speed of car A to
1 mile = 1609 m = 1.609 km (see, for example, the unit converter under this topic
So, the car's A speed is 100
. Car A is moving faster than car B.
Problem 3. Flow
The water supply well produces 18 gallons of water per minute from the subsurface aquifer.
How much is the flow rate in cubic meters per hour?
1 gallon(US Liquid) is equal to 0.003785
(or 3.785 liters).
Hence, 18 gallons/min = 18*0.003785
. The flow rate is 4.0878
Problem 4. Temperature
The Death Valley
in the Eastern California is the hottest place in the Western hemisphere with the highest measured temperature record of 134 °F (degree of Fahrenheit).
The world record is 57.8 °C (degree of Celsius) in Al 'Aziziyah, Libya
Compare these two temperature records.
To compare these two temperature records, let's express 134 °F in Celsius using the conversion formula from Fahrenheit to Celsius
°F to this formula, we have for temperature of Death Valley
So, the highest temperature in the Death Valley
is 56.67 °C against 57.8 °C in Al 'Aziziyah, Libya
