Length & Dimension Measurement

Discipline: Metrology | Tools Used: 4 | Servers: 3

Description

Precision length measurement: convert mm to m, calculate length plus width, area, and error.

Tools Used

• convert_length_mm_to_m from server-27 (streamable-http) - https://scp.intern-ai.org.cn/api/v1/mcp/27/Physical_Quantities_Conversion
• calculate_length_plus_width from server-25 (streamable-http) - https://scp.intern-ai.org.cn/api/v1/mcp/25/Geometry_and_mathematical_calculations
• calculate_area from server-25 (streamable-http) - https://scp.intern-ai.org.cn/api/v1/mcp/25/Geometry_and_mathematical_calculations
• calculate_absolute_error from server-26 (streamable-http) - https://scp.intern-ai.org.cn/api/v1/mcp/26/Data_processing_and_statistical_analysis

Workflow

1. Convert length mm to m
2. Calculate length plus width
3. Calculate area
4. Compute measurement error

Test Case

Input

{
    "length_mm": 150,
    "width_mm": 80
}

Expected Steps

1. Convert length mm to m
2. Calculate length plus width
3. Calculate area
4. Compute measurement error

Usage Example

Note: Replace sk-b04409a1-b32b-4511-9aeb-22980abdc05c with your own SCP Hub API Key. You can obtain one from the SCP Platform.
