Microsoft Windows Calculator App
The calculator app can be found on the start menu. It is a
pre-installed app on the Windows Operating System.
There are two main modes in which the Calculator app can be utilized. One mode is the calculator mode while the other is the converter mode.
Calculator Mode
The calculator has 4 modes which are the Standard, Scientific,
Programmer (or Developer), and Date Calculation modes.
Standard
The Standard mode appears as in the picture below.
And in full screen, it appears as below.
There are five memory functions which include Memory Add (M+), Memory Subtract (M-), Memory Store (MS), Memory Recall (MR) and Clear all Memory (MC). The shortcuts for these are Ctrl+P, Ctrl+Q, Ctrl+M, Ctrl+R, Ctrl+L respectively.The standard mode has a “keep on top” button which moves the app to the top right side of the screen and keeps it on top of any other items displayed on the screen.
Scientific
The Scientific mode appears as in the picture below and is similar to the scientific calculators.
Programmer
The Programmer mode appears as in the picture below.
Date Calculation
The Date Calculation mode appears as in the picture below.
Converter Mode
The converter mode features the following categories:
currency, volume, length, weight & mass, temperature, energy, area, speed,
time, power, data, pressure and lastly angle.
All these can be found by clicking on the navigation pane.
Currency
When selected, the currency converter starts with the
Afghanistan Afghani and ends with the Yemen Rial. There are about 130 countries’
currencies featured here.
Update rates
feature to display recent exchange rates
Volume
The volume converter may default to US Gallons to liters conversion when selected.
There are about 20 units of measuring volume featured here including pints, quarts, gallons, cubic inches, cubic feet to mention a few.
In the
conversion section, it can be seen that 100 US Gallons is equivalent to 378.5412
liters. At the bottom right of the screen, other equivalents are displayed
including 0.5 cubic yards, 0.38 cubic meters, 13.37 cubic feet, 83.27 UK gallons, 333.1 UK quarts, 400 US quarts and 1 bathtub.
In the second
example, 100 cubic meters is equivalent to 3,531,467 cubic feet
while the other equivalents include 130.8 cubic yards, 21,997 UK gallons, 26,417
US Gallon 87,988 UK quarts and 0.03 swimming pool.
The
fascinating part of the volume converter is the bathtub and swimming pools equivalents
3765 m3 = 1 swimming pool.
Note that an Olympic size swimming pool is specified as 50 meters
x 25 meters x 2 meters (Length x Width x Depth) as a minimum whereas it is 50 meters x 25 meters x 3 meters (recommended).
Length
Starting with
nanometer (nm) and ending at nautical miles, there are 11 units of measure of
length. Others include microns (µm), millimeters (mm), centimeters (cm),
meters (m), Kilometers (km), inches (in), feet (ft), yards and miles.
As displayed in the example below,
10 in is equivalent to 25.4 cm. And is also equivalent to 0.83 ft, 0.28 , 0.25
m, 254 mm, 254,000 µm, 254,000,000 nm and 1.36 hands

The weight
and mass may display pounds to kilograms conversion by default.
The units featured include carats, milligrams, centigrams, decigrams and grams. Others are dekagrams, hectograms, kilograms, metric tons, ounces, pounds, stone, US short tons and UK long tons.
As you may know, 100
pounds (1bs) is equivalent to 45.35924 kilograms (which can be approximated to 45.4
kilograms). Other equivalents include 7.14 stones, 0.05 ton (US), 0.05 ton, 0.04
ton (UK) 453.6 hg, 1,600 ounces (oz.) and 0.01 elephant
Approximately
8,800 pounds = 3,991.6 kg = 1 elephant
Temperature
The
temperature units featured here are Celsius, Fahrenheit and Kelvin.
In the
example below, 100°Celsius is equivalent to 212°Fahrenheit
and 373.1Kelvin.
Note that 0°C
= 32°F = 273.1 Kelvin.
Energy
The energy
converter, when selected may display the units of Joules (J) and Food Calories by
default. Other units featured include electron volts (eV), kilojoules (kJ),
Thermal calories, Foot-pounds (ft-lbs) and the British Thermal Units (BTU).
In the
example below, 1000 Joules is equivalent to 737.5621 foot-pounds (ft-lbs). It
is also equivalent to 1kJ, 0.95 BTU, 0.24 Kcal, 239 cal,
6,241,509,343,260,179,400,000 eV (6.24 x 1021 eV) and 0.11 battery.

other units featured are square millimeters (mm2), square
centimeters (cm2), square meters (m2), Hectares (ha), square
kilometers (km2), square inches (in2), square feet (ft2),
square yards, Acres and square miles.
An example
conversion shows 100 ft2 is equivalent to 9.290304 m2
(approximated to 9.3 m2). And this is equivalent to 11.11 (yd2),
14,400 (in2), 92,903 (cm2), 9,290,304 (mm2)
and 154 sheets of paper.
Speed
The speed
converter displays miles per hour to kilometers per hour conversion. Other
units featured are centimeters per second, meters per second, feet per second,
knots and Mach.
The Mach is
used as a unit of measurement for the speed of an object with respect to the speed
of sound. The speed of sound is the distance traveled per unit of time by a
sound wave as it propagates through an elastic medium. In air, sound travels
343 meters in one second.
In the
conversion example that follows, 90 miles per hour (mi/hr) is equivalent to 144.828
kilometers per hour (km/hr). it is also equivalent to 0.12 Mach, 40.23 m/s.
78.21 knots, 132 ft/s, 4,023 cm/s and 2 horses.
Time
The Time
converter can convert various values of time from one unit to another.
The units available range from microseconds to years, including milliseconds, seconds, minutes, hours, days and weeks.
In the conversion example, 365 days is equivalent to 525,600 minutes. It is also equivalent to 1 year, 52.14 weeks, 8,760 hours, 31,536,000 seconds, 31,536,000,000 milliseconds and 31,536,000,000,000 microseconds.
Power
The Power
converter may default to kilowatts to US horsepower units conversion when selected.
Other units featured are Watts (W), Foot-pounds per minute (ft-lbs/min), and the British Thermal Units per minute (BTU/min).
In the
example shown here, 1 Horsepower is equivalent to 745.6999 Watts (approximated
to 746 Watts), 0.75 kW, 42.41 BTU/min and 33,000 ft-lbs/min.
Data
The Data conversion
category may default to the Gigabytes to Megabytes conversion when selected.
There
are 34 units of data with which one can play around. Starting with bits
and bytes, the list includes Kilobits(Kb), Kibibits, Kilobytes (KB), Kibibytes
(KiB), Megabits (Mb), Mebibits, Megabytes (MB), Mebibytes (MiB), Gigabits (Gb), Gibibites,
Gigabytes (GB), Gibibytes (GiB), Terabits (Tb), Tebibits, Terabytes (TB), Tebibytes
(TiB). Others are Petabits (Pb), Pebibits, Petabytes (PB), Pebibytes (PiB), Exabits (Eb),
Exbibits, Exabytes (EB), Exbibytes (EiB), Zetabits (Zb), Zebibits, Zetabytes (ZB),
Zebibytes (ZiB), Yottabit (Yb), Yobibits, Yottabyte (YB) and Yobibytes ( YiB).
In the
conversion example, 1,000,000 kilobytes is equivalent to 0.001 terabytes. This
is also equivalent to 1 gigabyte, 0.93 GiB, 7.45, 8, 0.01, 0.01, 953.7, 1,000
MB, and 1.36 Cds.

Pressure
The Pressure
conversion feature, when selected, displays the atmosphere to bar conversion.
The units of measure of pressure featured here include Atmosphere (atm), Bar,
kilopascal (kP), millimeters of mercury (mmHg), pascals (P) and pound per
square inch (psi).
In the
example below, 100 kilopascals is equivalent to 1 bar. It is also equivalent to
0.99 atm, 14.5 psi, 760 mmHg and of course 100,000 pascals.
Angle
The angle
converter category defaults to degrees to radians conversion. The only other
unit measured is the gradians.
In the
example conversion, 360 degrees is equivalent to 6.283185 radians and 400
