Convert Chains to Spans

To convert chains to spans, the value is multiplied by the exact conversion factor 88 — that is, 1 chains = 88 spans. This tool applies that reference factor so results are precise.

1. 1

   Step 1

   Enter the value to convert.

2. 2

   Step 2

   Hit "Calculate" and the result is computed automatically.

3. 3

   Step 3

   Use the result while keeping the context and units in mind.

4. 4

   Step 4

   The breakdown under the result lists value × 88 — read it before copying the spans figure into your work.

5. 5

   Step 5

   Adjust the input and compare scenarios: a round anchor like 10 chains gives 880 spans — an easy mental check of the factor.

• 1

  This page converts Chains to Spans using the exact reference factor 88. That is the standard figure, so the results here match reference tables rather than rounded approximations.

• 2

  With very large or very small Chains values, read the full Spans result before copying it — scientific notation is easier to misjudge than a plain number, especially across several orders of magnitude in one conversion.

• 3

  Round only the final result: keep full precision while converting Chains to Spans and round once at the end, because rounding every intermediate step lets drift accumulate until the final figure drifts from its true value.

• Decimal separators corrupt input silently: a comma can be read as a thousands separator and shift a Chains value by ×1000. Control check: enter 2.5 and confirm the result equals 220 Spans before trusting larger values.

• Order-of-magnitude check: 1 Chain = 88 Span exactly, so type 1 first — a wildly different spans figure means a stray comma, wrong field, or flipped direction before you convert real values.
