Converting Measurements | Maths

Converting meaurements is to multiply or to divide height, length and width of something. There are four main measurements mm, m, cm and km. 

When a number is multiplied by 10 the decimal point moves once to the right.

For example: If I mulitply 50.0 by 10 the decimal point moves to the right that makes it a bigger number. Making it 500.

When a number is divided by 100 the decimal point moves twice to the left.

For example: If I divide 500.0 by 100 the decimal point moves twice to the left that makes it a smaller number. Making it 5.00.

When multiplying by ten you can't "add" a O onto the end of the number, but you can shift the place value. The zero's indicate how many times you shift the place value. For example 10 moves once as it has 1 zero, where as 10000 would move 4 times as it has 4 zeros.

Place value house can help covert measurements.
