1, Grade Three Mathematics: Common conversion formulas of units (length, area, weight, RMB, time).

2. In primary school mathematics learning, unit conversion runs through. It mainly deals with unit conversion, including length, area, volume, weight, RMB and time conversion.

3. Because the conversion values are not uniform, many primary school students easily confuse these conversion values, which leads to mistakes in exams, loss of points, and sometimes jokes in life.

Conversion:

1 km = 0.62 1 mile.

1 m = 3.28 1 ft) = 1.094 yards.

1 DMM =1Mi Hu meter (cmm)= 1 silk =0.0 1 mm =0.00 1 cm.

1 cm) = 0.394 inch (inch).

1 cm =10mm.

1 decimeter (DM) =10cm.

10 9 nm = 1 meter (meter).

10 6 nm = 1 mm (mm).

10 3 nm = 1 micron (micron).

1 nm = 10 Amy (remember? )。

1 Amy = 10- 10 meter (m).

1 angstrom (? ) = 0. 1 nm.

1 mile) = 1.609 km (km).
