About Foot (ft) and Chain (ch)
What is a Foot (ft)?
A foot (ft) is a unit of length widely used in construction, surveying layout planning, spatial measurements, and dimensional scaling.
1 foot = 12 inches
This unit is practical for on-site measurement tasks where direct physical distance needs to be evaluated and recorded.
What is a Chain (ch)?
A chain (ch) is a measurement unit historically applied in field surveying and land mapping.
1 chain = 66 feet
Chains appear in property descriptions, field boundary layout notes, and archival land documentation, maintaining continuity in recorded measurement history.
What Does This Converter Do?
This converter changes feet (ft) into chains (ch) to allow modern measurements to align with documentation and plotting frameworks that reference chain units.
How to Convert Feet to Chains
To convert feet (ft) to chains (ch), use:
Chains = Feet ÷ 66
or expressed as a ratio:
1 foot = 1 ÷ 66 chain
This indicates that a single foot is a small fraction of a chain.
Why Convert from Feet to Chains?
Converting feet to chains is useful when:
Reviewing boundary sizes in old surveying records
Matching field notes with archived mapping formats
Comparing recent measurements with earlier land layout descriptions
Interpreting property dimensions recorded during earlier surveying periods
Chains provide a stable reference unit in long-form land measurement history.
What is One Foot in Chains?
1 foot = 1 ÷ 66 chain
Approximately equal to:
1 foot ≈ 0.01515 chain
What is One Chain in Feet?
1 chain = 66 feet
Differences Between Feet and Chains
Unit | Primary Application | Context of Use |
|---|---|---|
