Conversion formula creation assistance

[Cadbury204]

Hi,

I'm working on a project that uses a mass air flow sensor. It outputs a signal in hertz which relates to grams per second.

I am trying to create a formula that I can use to easily convert the Hz to G/s.

I have only been able to get a few samples of information to assist in the creation of the formula.

Is it possible to generate a formula from these data points?

Note: some of this data may be off by a few percent.

G/s Hertz
0 1700
2.75 4300
5.8 5680
3.97 4880
3.7 4800
6 5800
10.2 7150
12.4 7800
2.8 4300
3.1 4500
2.75 4300
13.53 8200
15.6 8800
22 9800
26 10500
28 11000
35 12100
44 13000

Any help is appreciated

Have you tried plotting this data?

I have put it into a graph in excel. But I'm not to sure where to go from here.

A good start would be to add a linear trend line, use the formula for the trend line as your model.
