: one of a set of fundamental units in a system of measurement that is based on a natural phenomenon or established standard and from which other units may be derived The base units of the International System of Units are the meter, kilogram, second, ampere, kelvin, mole, and candela.

The SI unit of time is second. There are seven base units is SI. They are meter (length), kilogram (mass), second (time), Ampere (current), Kelvin (temperature), candela (luminous intensity), mole (amount of substance). For example, Force – The SI unit is Newton, Pressure – SI unit is Pascal etc.

SI derived units are units of measurement derived from the seven base units specified by the International System of Units (SI). They are either dimensionless or can be expressed as a product of one or more of the base units, possibly scaled by an appropriate power of exponentiation.

Help to show another person the exact amount you have. Assist in solving a mathematical problem, especially in chemistry, where you can follow the units to get to the answer. Show which measurement system the person is using (i.e. metric or standard)

A unit rate is a rate with 1 in the denominator. If you have a rate, such as price per some number of items, and the quantity in the denominator is not 1, you can calculate unit rate or price per unit by completing the division operation: numerator divided by denominator.

So unit rates are ratios comparing two quantities with different units. And conversion factors, which can be used to convert between different units, can also then be used to convert between different rates.

What do all conversion factors have in common? The numerator and the denominator have the same value expressed in different units.

There are 3.28084 feet per meter. So if you want to convert meters to feet using your own calculator, just multiply your number of meters by 3.28084.

Conversion refers to the process of changing or converting the class of a word without changing its form. The word email, for instance, can be used as a verb in Modern English though it was only a noun in the past. Examples: Noun to verb: bottle (The wine was brewed in France but bottled in Hong Kong.)

Examples of conversion factors include:

• 1 gallon = 3.78541 liters (volume)
• 1 pound = 16 ounces (mass)
• 1 kilogram = 1,000 grams (mass)
• 1 pound = 453.592 grams (mass)
• 1 minute = 60000 milliseconds (time)
• 1 square mile = 2.58999 square kilometers (area)

A conversion occurs when a visitor to your website completes a desired goal, such as filling out a form or making a purchase. The percentage of total visitors that convert is called your conversion rate. Depending on your site’s or business’s goals, conversion types might include: Online sales. Leads.

the act or process of converting; state of being converted. change in character, form, or function. a physical, structural, or design change or transformation from one state or condition to another, especially to effect a change in function: conversion of a freighter into a passenger liner.
