what is units of imu message

[vishalleo1]

Hello ,
Thanks to get the IMU message from the bricks 2.0 imu.
Here we get the IMU message, we run the code so we get the IMU message as bellow,
header:
seq: 205
stamp:
secs: 1642586957
nsecs: 160344286
frame_id: "/base_link"
orientation:
x: 0.999328553677
y: -0.00701947137713
z: -0.0111701153219
w: -0.0352804735303
orientation_covariance: [0.1, 0.1, 0.1, 0.1, 0.1, 0.1, 0.1, 0.1, 0.1]
angular_velocity:
x: 0.558505356312
y: 0.0
z: -0.558505356312
angular_velocity_covariance: [0.1, 0.1, 0.1, 0.1, 0.1, 0.1, 0.1, 0.1, 0.1]
linear_acceleration:
x: 0.0
y: 300.0
z: -3400.0
linear_acceleration_covariance: [0.1, 0.1, 0.1, 0.1, 0.1, 0.1, 0.1, 0.1, 0.1]

standard unit of imu liner acceleration is m/ss,
as per message here we get the liner acceleration is in mm/ss?

question is what is unit of angular_velocity of IMU?
for liner acceleration mm/s*s is correct?
