Unit of volume:
Cubic meter (m 3), decimeter cubic meter (dm^3), centimeter cubic meter (cm^3), millimeter cubic meter (mm^3), liter (l), milliliter (mL) sometimes.
1m^3= 1000dm^3, 1dm^3= 1000cm^3, 1cm^3= 1000mm^3, 1dm^3= 1l, 1cm^3= 1ml, 1l= 1000ml.
1000 microsecond, millisecond and second rate.
That is, 1 sec = 1000 ms = 1000000 microseconds.
The ratio between 60 seconds, minutes and hours.
That is 1 hour =60 minutes =3600 seconds.
The ratio between 24 hours and days.
1 day =24 hours
Between days and years, the general ratio is 365.
1 year =365 days
Forward speed between unit and weight unit
microgram
Microgram, mass unit, symbol μg (English: Microgram).
1 microgram is equal to one millionth of a gram (10-6 grams).
1 0,000 μ g = 1 mg
1 1,000,000 μ g = 1 g
1 000,000,000 μ g = 1 kg
Mg mg, the unit of mass, is one thousandth of a gram.
1 mg = 1 000 micrograms.
1 000 mg = 1 g.
1 000 000 mg = 1 kg
The symbol g is equal to one thousandth of a kilogram. The weight of one gram is equivalent to the weight of one cubic centimeter of water at room temperature, which is equivalent to the mass of a cross clamp.
1 ton = 1, 000,000 grams
1 kg = 1 1,000 g
1 mg = 0.00 1 g.
1 μ g = 0.000 00 1
Kilogram, also known as kilogram, is an international basic unit of mass, with the symbol kg.
definition
An international kilogram prototype (cylinder) made of Pt-Ir alloy, with a bottom diameter of 39 mm and a height of 39 mm, has a specified mass of 1 kg. It is currently kept in the International Bureau of Metrology in Paris, France.
Unit conversion
1 kg = 0.00 1 ton
1 kg = 1 1,000 g
1 kg = 1, 000,000 mg
1 kg = 1.000 μ g
A unit of mass measurement per ton, with the symbol T or T. 。
1 ton = 1000 kg
The propulsion rate between two adjacent area units is 100, except for square meters and hectares, 10000.
1 square decimeter = 100 square centimeter
1 m2 = 100 square decimeter
1 ha = 1 10,000 m2
1 km2 = 100 hectare
