Your weight on other planets

We made some cool spreadsheets in maths today - here's a couple of examples:

Christian's spreadsheet
Nina's spreadsheet

Can you work out how they made them?

Here's the data you'll need for my group's maths lesson today, where we're making a spreadsheet to calculate your weight on other planets:

Celestial Body	Gravitation Factor Relative to Earth
Sun	27.9
Mercury	0.38
Venus	0.91
Earth	1
Moon	0.17
Mars	0.38
Jupiter	2.54
Saturn	1.08
