Liquids are literally the lifeblood of the human condition. A good 50-65 percent of the adult human body is made of water. Humans, in general, can last only up to a week without a definite source of liquids. Liquids are present in our bodies, in our foods, in the objects we handle and the substances we cannot. With these things being taken into account, it was only logical that society invent several ways of measuring and quantifying liquids. Thanks to advancements in mathematics and many other fields of science, we are now able to compute how many milliliters in a liter there are, in addition to many other forms of measurement conversion.
Systems of Measurement
The need for an international system of measurement is something that should not be taken lightly. The pricing structure of several commodities relies strongly on a unified system that all citizens can agree to. This is extremely important for liquids which are intangible and thus more difficult to quantify. In cases such as this, scientific practices make use of containers in order to convert liquids into forms that can be easily quantified and measured. First, before we can determine how many milliliters in a liter there are, it is essential to have a basic understanding of the liter and how it became a standard of liquid measurement.
What is a Liter?
The liter, denoted by the symbol l, is an independent unit of measurement used to determine the volume of any specific amount of water. The term ‘liter’ is based on the word litron, a measurement unit of Greek and Latin origins. The earliest working definition of the liter required a series of additional measurements. The liter, as defined in 1901, was the amount of one kilogram’s worth of water at 4 °C and 760 millimeters of mercury pressure. Today, it is defined as the amount of water capable of filling a space measuring one cubic decimeter – that is, a space occupying 10 centimeters by 10 centimeters by 10 centimeters.
Conversion and Conversion Factors
The key to finding out how many milliliters in a liter is to understand conversion factors. Conversion factors are the standards that are followed in changing the measurement of one object to another standard of measurement. Commonly, prefixes – words attached to the beginning of the base unit – provide a clue as to the proper conversion factor for each standard. In this case, milli, the prefix of the word milliliter, stands for one thousandth. A thousandth (with the -th) is defined as one part of a thousand. Thus, in order to form one liter of a substance, 1000 milliliters are required. Thus, the final conversion standard appears as:
1 liter = 1000 milliliters
A company receives an order of 75 liters of water for delivery. How much is the volume of the order in milliliters?
Conversion Factor: 1 liter = 1000 milliliters
Since we have determined the conversion factor for liter-milliliter conversion, all that’s left is to plug in the values. The equation then becomes:
1 liter = 1000 milliliters
75 liters = ? milliliters
75 liters (1000) = 75000 milliliters
Thus, 75 liters is 75,000 in milliliters.
