Here are some common units of time measurement:

Millisecond

Millisecond (abbreviation: ms) is a thousandth (1/1,000) of a second.

Second

Second (SI symbol: s), sometimes abbreviated sec., is a unit of time, and is the International System of Units (SI) base unit of time. It may be measured using a clock.

Day

Day is traditionally defined as the span of time it takes for the Earth or a celestial body (such as an other planet or a moon) to make a single rotation with respect to a star, measured most accurately from local noon to local noon.

Week

Week is a time unit equal to seven days.

Month

Month is a unit of time, used with calendars, which was first used and invented in Mesopotamia, as a natural period related to the motion of the Moon; month and Moon are cognates. The traditional concept arose with the cycle of moon phases; such months (lunations) are synodic months and last approximately 29.53 days.

Quarter

Quarter is one fourth, ¼, or 25%. Quarter as a unit of time, is equal to 3 month or 1/4 of a year.

Year

Year is the orbital period of the Earth moving around the Sun. For an observer on Earth, this corresponds to the period it takes the Sun to complete one course throughout the zodiac along the ecliptic.

Decade

Decade is a period of 10 years. The word is derived (via French) from the Ancient Greek dekas which means ten.

Century

Century (from the Latin centum, meaning one hundred) is one hundred consecutive years. It is also a Roman term.

Millennium

Millennium (plural millenniums or millennia) is a period of time equal to one thousand years (1,000) (from the Latin phrase mille, thousand, and annus, year), often but not necessarily related numerically to a particular dating system.

Here are some common units of temperature measurement:

Celsius

Celsius is a scale and unit of measurement for temperature. It is named after the Swedish astronomer Anders Celsius (1701–1744), who developed a similar temperature scale two years before his death. The degree Celsius (°C) can refer to a specific temperature on the Celsius scale as well as a unit to indicate a temperature interval, a difference between two temperatures or an uncertainty. The unit was known until 1948 as centigrade.

Fahrenheit

Fahrenheit is the temperature scale proposed in 1724 by, and named after, the German physicist Daniel Gabriel Fahrenheit (1686–1736).

Kelvin

Kelvin is a unit of measurement for temperature. It is one of the seven base units in the International System of Units (SI) and is assigned the unit symbol K. The Kelvin scale is an absolute, thermodynamic temperature scale using as its null point absolute zero, the temperature at which all thermal motion ceases in the classical description of thermodynamics.

Rankine

Rankine is a thermodynamic (absolute) temperature scale named after the Scottish engineer and physicist William John Macquorn Rankine, who proposed it in 1859.

Here are some common units of storage measurement:

Bit

Bit or binary digit is the basic unit of information in computing and telecommunications; it is the amount of information stored by a digital device or other physical system that exists in one of two possible distinct states. These may be the two stable states of a flip-flop, two positions of an electrical switch, two distinct voltage or current levels allowed by a circuit, two distinct levels of light intensity, two directions of magnetization or polarization, etc.

Kilobit

Kilobit is a multiple of the unit bit for digital information or computer storage. The prefix kilo (symbol k) is defined in the International System of Units (SI) as a multiplier of 10³ (1 thousand).

Megabit

Megabit is a multiple of the unit bit for digital information or computer storage. The prefix mega (symbol M) is defined in the International System of Units (SI) as a multiplier of 10⁶ (1 million).

Gigabit

Gigabit is a multiple of the unit bit for digital information or computer storage. The prefix giga (symbol G) is defined in the International System of Units (SI) as a multiplier of 10⁹ (1 billion, short scale).

Terabit

Terabit is a multiple of the unit bit for digital information or computer storage. The prefix tera (symbol T) is defined in the International System of Units (SI) as a multiplier of 10¹² (1 trillion, short scale).

Petabit

Petabit is a multiple of the unit bit for digital information or computer storage. The prefix peta (symbol P) is defined in the International System of Units (SI) as a multiplier of 10¹⁵ (1 quadrillion, short scale).

Byte

Byte is a unit of digital information in computing and telecommunications, that most commonly consists of eight bits. Historically, a byte was the number of bits used to encode a single character of text in a computer and it is for this reason the basic addressable element in many computer architectures.

Kilobyte

Kilobyte is a multiple of the unit byte for digital information. The prefix kilo means 1000 in the International System of Units (SI), therefore 1 kilobyte is 1000bytes. The recommended unit symbol for the kilobyte is kB or kbyte. The kilobyte is often considered to be 1024 (2¹⁰) bytes in most fields of computer science and information technology.

Megabyte

Megabyte is a multiple of the unit byte for digital information storage or transmission with two different values depending on context: 1048576 bytes (2²⁰) generally for computer memory; and one million bytes (10⁶) generally for computer storage.

Gigabyte

Gigabyte is a multiple of the unit byte for digital information storage. The prefix giga means 10⁹ in the International System of Units (SI), therefore 1 gigabyte is 1000000000 bytes. Historically, the term has also been used in some fields of computer science and information technology to denote the gibibyte, or 1073741824 (1024³ or 2³⁰) bytes.

Terabyte

Terabyte is a multiple of the unit byte for digital information. The prefix tera means 10¹² in the International System of Units (SI), and therefore 1 terabyte is 1000000000000 bytes, or 1 trillion (short scale) bytes, or 1000 gigabytes.

Petabyte

Petabyte is a unit of information equal to one quadrillion (short scale) bytes, or 1000 terabytes.
