It is moderate and generally manageable, depending on design standards and weather conditions.
Practical Context
How this exact question appears in real work and what the result helps you decide.
Example 1: Engineering Communication
Who Asks This Question?
Rail, road, and drainage engineers ask this when one stakeholder uses permille while another expects degrees. For this exact query: How steep is 12 permille in degrees?
What This Answer Tells You
The degree value translates the same slope into a format that survey tools and some design reviews use directly. For this case: 12‰ is about 0.687 degrees.
Example 2: Site Briefing And Safety
Who Asks This Question?
Field supervisors ask this when describing incline severity to crews not used to permille notation. For this exact query: How steep is 12 permille in degrees?
What This Answer Tells You
The answer gives an intuitive angle reference for planning equipment operation and safety controls. For this case: 12‰ is about 0.687 degrees.
