Appendix B: Unit Conventions

All numeric specification fields in the RoboCata Standard follow these unit conventions. Implementations must use the specified units to ensure comparability.

Length / Distance	Millimeters	mm	dimensions_height_mm, reach_mm
Speed (linear)	Meters per second	m/s	speed_mobile_ms
Temperature	Degrees Celsius	°C	operating_temp_min_c, operating_temp_max_c
Voltage	Volts	V	power_voltage_min, bat_voltage_v
Power	Watts	W	power_consumption_normaluse_w
Energy	Watt-hours	Wh	bat_capacity_wh
Time	Hours	h	bat_runtime_hours, bat_charge_time_hours
Sound Level	Decibels (A-weighted)	dB(A)	noise_level_db
