acceleration in m/s^2

[hatt0002]

Hi, does anyone knows how to get acceleration in m/s^2 from the i2cdevlib OUTPUT_READABLE_WORLDACCEL? Further more, how to convert acceleration to velocity in m/s?
Thanks in advance

Dont know if what i am saying is correct but

You get outpu X Y Z ( 3 axis)  2 bytes for each axe 

each value ( 2bytes) is signed so you convert them to  -32768 till +32768 depend on your scale ( -+2G 4G 8G 16G) you divine your output.

for example for 16G you divine output/2048 (if you have stable the sensor Z axe will show you 1 gravity , so if it show you 2048 the accelerometer is on +-16G mode)

 

You get samples in internal, if you get every 0.001sec you -> velocityZ =accelerationZ*0.001*G => velocityZ=accelerationZ*0.001*9.8

G=9.8m/s2

 

But Sensor are not accurate your sample interal is not enough so the velicity probably will be far from real (and distance quad far )

Thankyou so much. You saved me alot of time
