Hello Paige!

1. This is a metric conversion for mass. The prefix kilo means 1000 so a kg is 1000 g. If we keep in mind the units, we can convert:

15kg * (1000g/1kg) = 15000g

2. To convert Farenheit to Kelvin, we first need to convert farenheit into celsius using the following equation:

C = 5/9 (F - 32)

If we plug in F = 90:

C = 5/9 (90-32) = 32.22 degrees C

Then we can always add 273.15 to any celsius temperature to convert it to Kelvin:

32.22 + 273.15 = 305. 37 K

3. Going from celsius to farenheit involves solving the previous equation for F:

F = (9/5)C + 32

F = (9/5)*(32) + 32

F = 89.6 degrees F

4. This is probably the easiest conversion! We did this in already, we just need to add 273.15 to go from celsius to kelvin:

32 + 273.15 = 305.15 K
