Liters and milliliters are unit of volume, and milliliters correspond to cubic centimeters. L is expressed as L in the international system of units, and its auxiliary unit is ml ml. The propulsion rate between milliliter and liter is 1000, that is, 1 liter is equal to 1000 ml, and 1 ml is equal to 0.00 1 liter. If you want to convert liters into milliliters, you can directly use this conversion ratio to calculate.
In an era when science and technology are not developed enough and standard weights and measures are not popular enough, people generally measure the weight of grain in liters, buckets and other capacity units, which is the imprint of the times. In this metering system, one liter is one tenth of a barrel, and one liter of rice is about 2000 grams (that is, 4 kilograms).
Conversion of common units in mathematics;
I. Units of distance and length
1 km = 1 km, 1 km = 1000 m.
1 m = 10 decimeter, 1 decimeter = 10 cm.
1 cm = 10 mm, one room =30 Li.
One mile =500 meters, one foot =33 centimeters.
Second, the area unit
1 m2 = 100 square decimeter, 1 square decimeter = 100 square centimeter.
1 cm2 = 100 mm2, 1 hectare = 10000 m2, 1 mu = 666.666m2.
Third, unit of volume.
1 m3 = 1000 cubic decimeter, 1 cubic decimeter = 1000 cubic centimeter.
1 cubic centimeter = 1000 cubic millimeter, 1 liter = 1 cubic decimeter = 1000 ml, 1 ml = 1 cubic centimeter.
Fourth, the unit of weight
1 ton = 1000 kg, 1 kg = 1000 g = 1 kg =2 kg.
Once =50 kg, one money =3 g, and one gentleman =30 kg.
A barrel = 12kg, a stone = 120kg, and a kilogram = 2kg.
One catty =500 grams, one or two =50 grams.
