How to Calculate 360 Degrees Into House Degrees Astrology

What Are House Degrees in Astrology?

The 12 houses of the horoscope represent different areas of life, each spanning 30 degrees (360° ÷ 12 = 30° per house). House degrees indicate where a planet is positioned within these life areas. For example, a planet at 15° in the first house would be in the first house, while 30° would place it at the cusp between the first and second houses.

Understanding house degrees helps astrologers analyze how planets influence specific aspects of a person's life. Each house has unique characteristics, and knowing a planet's exact position within a house provides deeper insights into its effects.

Conversion Method

To convert 360 degrees into house degrees, follow these steps:

1. Divide the total degrees (360) by the number of houses (12) to determine the degrees per house: 360° ÷ 12 = 30° per house.
2. Identify the house number by dividing the given degrees by 30 and rounding up to the nearest whole number.
3. Calculate the exact position within the house by finding the remainder when the given degrees are divided by 30.

For example, if a planet is at 75°, the calculation would be:

• 75 ÷ 30 = 2.5 → House 3 (rounded up)
• 75 MOD 30 = 15° → Positioned 15° into House 3

Example Calculation

Let's convert 120° into house degrees:

1. Divide 120 by 30: 120 ÷ 30 = 4 → House 4
2. Find the remainder: 120 MOD 30 = 0 → Positioned exactly at the cusp between House 4 and House 5

This means the planet is at the boundary between the fourth and fifth houses, indicating a potential transition between these life areas.

Common Mistakes to Avoid

When converting degrees to house degrees, avoid these common errors:

• Rounding errors: Always round up to the nearest whole number when determining the house number.
• Incorrect modulus calculation: Ensure you're using the correct modulus operation to find the position within the house.
• Ignoring house cusps: Remember that a position exactly at 30°, 60°, etc., is at the cusp between two houses.

Interpreting House Degrees

Once you've converted degrees to house degrees, consider these interpretation guidelines:

• Planetary strength: Planets near the middle of a house (10-20°) have stronger influence than those near the cusp.
• Aspects: Check if the planet forms significant aspects with other planets in the same house.
• House rulers: Consider the ruler of the house where the planet is positioned for additional insights.

For example, a planet at 15° in the first house (House 1) would be influenced by the first house ruler (usually Mars or Aries) and would have moderate strength in that house.
