6.8 - Mass

How do you convert to a different unit?

Key Rules of Converting
 * To convert to a larger unit, divide your number by 1000
 * To convert to a smaller unit, multiply your number by 1000

For Example: Q. Convert 3kg to grams A. 3000g

How to work it out: Because grams are a smaller unit than kilograms, to convert the 3kg, simply multiply 3 by 1000. There's your answer.

How do you work out which is heavier? <span style="display: block; font-family: 'Trebuchet MS',Helvetica,sans-serif; font-size: 115%; text-align: center;">Example: <span style="display: block; font-family: 'Trebuchet MS',Helvetica,sans-serif; font-size: 115%; text-align: center;">Q. If the mass of one box is 12.34kg and the mass of another box is 123500g, which is heavier? <span style="display: block; font-family: 'Trebuchet MS',Helvetica,sans-serif; font-size: 115%; text-align: center;">A. The box weighing 123500g is heavier.

<span style="display: block; font-family: 'Trebuchet MS',Helvetica,sans-serif; font-size: 115%; text-align: center;">How to work it out: <span style="display: block; font-family: 'Trebuchet MS',Helvetica,sans-serif; font-size: 115%; text-align: center;">Your first thought might automatically be that the box weighing 12.34kg is heavier, just because kg are a bigger unit than g, but work it out before you presume its the first box. <span style="display: block; font-family: 'Trebuchet MS',Helvetica,sans-serif; font-size: 115%; text-align: center;">Even if you're pretty sure you know the answer, it's a good idea to check by working it out, before you write your answer. <span style="display: block; font-family: 'Trebuchet MS',Helvetica,sans-serif; font-size: 115%; text-align: center;">The first thing you need to do to solve the problem is convert the g to kg or vice-versa. Doing this will give you your answer.

<span style="display: block; font-family: 'Trebuchet MS',Helvetica,sans-serif; font-size: 115%; text-align: center;">Adding mass is fairly easy. All you need to do is convert the units so they are the same, then simply add them together. <span style="display: block; font-family: 'Trebuchet MS',Helvetica,sans-serif; font-size: 115%; text-align: center;">The same goes for subtracting, multiplying, dividing mass etc. <span style="color: #12ed23; font-family: 'Trebuchet MS',Helvetica,sans-serif; font-size: 115%;">__Review Questions__  <span style="display: block; font-family: 'Trebuchet MS',Helvetica,sans-serif; font-size: 115%; text-align: left;"><span style="color: #12ed23; font-family: 'Trebuchet MS',Helvetica,sans-serif; font-size: 115%;">1) Convert:  <span style="display: block; font-family: 'Trebuchet MS',Helvetica,sans-serif; font-size: 115%; text-align: left;">a) 12kg to g b) 400mg to g c) 34g to kg d) 680mg to kg  <span style="display: block; font-family: 'Trebuchet MS',Helvetica,sans-serif; font-size: 115%; text-align: left;"><span style="color: #12ed23; font-family: 'Trebuchet MS',Helvetica,sans-serif; font-size: 115%;">2) Order from smallest to largest: <span style="display: block; font-family: 'Trebuchet MS',Helvetica,sans-serif; font-size: 115%; text-align: left;">a) 2kg b) 3080g c) 24g d) 48.99mg e) 39kg <span style="display: block; font-family: 'Trebuchet MS',Helvetica,sans-serif; font-size: 115%; text-align: left;"><span style="color: #12ed23; font-family: 'Trebuchet MS',Helvetica,sans-serif; font-size: 115%;">3) 26.3457kg + 26.26g =

<span style="font-family: 'Trebuchet MS',Helvetica,sans-serif; font-size: 115%;">You can determine whether a network is transversable or not by how many odd and even vertexes it has.
