Sand Calculation Formula:
From: | To: |
The Sand Calculator UK estimates the amount of sand needed for construction projects (e.g., paving, mortar) based on area, depth, and standard UK sand density (1600 kg/m³).
The calculator uses the following formula:
Where:
Explanation: The calculation accounts for the volume of sand needed and converts it to weight using standard density.
Details: Proper sand estimation ensures you purchase the correct amount for your project, avoiding waste or shortages that could delay work.
Tips: Measure the area accurately in square meters and determine the required depth of sand. The density is fixed at 1600 kg/m³ for UK standard building sand.
Q1: Does this work for all types of sand?
A: This uses standard building sand density. Sharp sand or other types may have slightly different densities.
Q2: How do I measure the area?
A: For rectangular areas: length × width. For irregular shapes, break into smaller rectangles and sum the areas.
Q3: What depth should I use for paving?
A: Typically 50-100mm (0.05-0.1m) for paving bedding, but consult your project specifications.
Q4: How many bags will I need?
A: Divide the total kg by bag size (typically 25kg bags for building sand).
Q5: Does this account for compaction?
A: No, you may need 10-20% extra sand to account for compaction depending on the project.
