# Working with Unreal Engine
- We are using Unreal Engine 5.5.4, so be extremely cautious of using deprecated or outdated APIs, includes or practices.
## Coordinate System
In the Unreal Editor, the following colors are associated with the coordinate axes:
X-axis: Red
Y-axis: Green
Z-axis: Blue
UE's Z-up, left-handed coordinate system is defined as follows:
The Z-axis determines how far up and down along a vertical line an actor is located.
Positive values are upwards.
The Y-axis determines how far to the left or right an actor is located.
Positive values are to the right.
The X-axis determines how far forward or backward an actor is located.
Positive values are forward.
## Units
Unreal Engine (UE) defaults to the following International System (SI) units for measurement:
Quantity Unit
Distance/Length Centimeters (cm)
Mass Kilograms (kg)
Time Minutes (min), Seconds (s)
Angles Degrees (deg)
Speed/Velocity Meters per Second (m / s)
Temperature Celsius (C)
Force Newtons (N)
Torque Newton Meters (N • m)
