Divide (by 100) 100 cm = 1 m 50 cm = 0.5 m and so on.

Remember there are 1000 mm in 1 m To change 'mm' to 'm' multiply by its reciprocal. algebraically mm X 1/m

The milli- prefix means one thousandth. → 1 mm is one thousandth the length of 1 m To convert m to mm: multiply by 1000 To convert mm to m: divide by 1000.

??m x 1 mm/10^-3 m

To convert from millimeters (mm) to meters (m), divide the value in millimeters by 1000. So, to convert 488 mm to meters, divide 488 by 1000: 488 mm รท 1000 = 0.488 m.

??m x 1 mm/10^-3 m

The milli- prefix means 1/1000 (one thousandth) → 1 mm = 1/1000 m The centi- prefix means 1/100 (one hundredth) → 1 cm = 1/100 m But in equivalent fractions 1/100 = (1×10)/(100×10) = 10/1000 = 10 × 1/1000 → 1 cm = 1/100 m = 10/1000 m = 10 × 1/1000 m = 10 mm Thus for every 1 cm there are 10 mm, but this can also be written as for every 10 mm there is 1 cm. Thus to convert cm to mm multiply by 10; and to convert mm to cm divide by 10. To help remember whether to multiply of divide: When going from a bigger unit (cm) to a smaller unit (mm) there will be more of them so multiply When going from a smaller unit to a bigger unit (you are clumping them together and so) there will be fewer of them so divide.

When you change from a larger unit to a smaller unit there will be more of them; thus you multiply. eg millimetres are smaller than centimetres. Thus it requires many more of them to measure the same distance. Thus when converting metres to millimetres a multiplication will be required. If you draw a line 3.5 cm long with your rule, and then measure it in mm you will find that it takes 35 mm. If you look closely you will see than 1 cm = 10mm, thus 3.5 cm = 3.5 × 10 mm = 35 mm.

To convert from millimeters (mm) to meters (m), divide the value in millimeters by 1000. So, to convert 488 mm to meters, divide 488 by 1000: 488 mm รท 1000 = 0.488 m.

The result of converting 1.6 meters to millimeters is 1600 millimeters. To convert meters to millimeters, you multiply by 1000 since there are 1000 millimeters in a meter.

To convert from a larger unit to a smaller unit you would multiply. Ex: 5 km = 5000 m Where 1 km = 1000 m <><><><><> It depends on which factor you are multiplying or dividing by. It can go either way. To convert from ounces to grams, for instance, you can divide by 28.350, or you can multiply by 0.035273.

Divide by 100.

Multiply by 1000.

divide it by 1000 (there are 1000 mm in a meter)
