Speed Conversion Worksheets — km/h to m/s (Free Printable)

Speed conversion between kilometers per hour and meters per second is the most-used unit switch in middle-school physics — and it links straight to UnitFig converters. Every problem uses the exact factor 1 m/s = 3.6 km/h, so students can check any answer with the site. These sheets give clean, repeatable practice without a calculator dependency.

Teaching tips for speed

  • Anchor the factor: 1 m/s = 3.6 km/h. To go km/h → m/s divide by 3.6; to go m/s → km/h multiply by 3.6.
  • Estimate first: 10 m/s is about 36 km/h (city speed), 100 km/h is about 28 m/s (highway). A sane estimate catches a flipped operation instantly.
  • Keep units in the answer — "m/s" or "km/h" is half the grade. Writing the unit forces the student to confirm the direction of the conversion.

Common mistakes to watch for

Multiplying when converting km/h → m/s (or vice versa).
m/s is the smaller number: 36 km/h = 10 m/s. Divide by 3.6 to shrink km/h into m/s; multiply to grow m/s into km/h.
Dropping the unit from the answer.
Always write the unit. "10" is incomplete; "10 m/s" is the answer and confirms the direction.

Grade & standards alignment

These speed worksheets target the Grades 6–9 band of the Common Core State Standards for Mathematics (CCSSM). The relevant CCSS math domains are:

The CCSSM are public, open-license standards; this alignment is provided for planning and is not an official endorsement by the standards authors.

How these worksheets are built (accuracy & trust)

  • Problems are generated by a deterministic engine using exact integer and rational arithmetic — answers are reduced to lowest terms and never rely on floating-point rounding, so they match the matching UnitFig converter.
  • Grade presets follow the CCSSM progression above; pick a grade to get age-appropriate number ranges.
  • Content is reviewed for accuracy and refreshed each year (2026). Worksheet copy and examples are original and written for classroom use.

Safe for classrooms — zero data collection

UnitFig collects no personal information from children or any visitor. Worksheets run entirely in the browser: no account, no name or email, and student answers never leave the device. We follow a COPPA-aligned, zero-collection design so teachers and parents can use these sheets without a signup wall or privacy concern. See our Privacy Policy.

Frequently Asked Questions

What is the exact km/h to m/s factor?

1 meter per second equals exactly 3.6 kilometers per hour. The worksheet engine applies this factor, matching the UnitFig speed converter.

What grade is speed conversion for?

It appears in grade 6–9 physical science (motion and speed units). It is also used constantly in sports and driving contexts.

Can I check answers with a UnitFig tool?

Yes — the speed conversion worksheets use the same 3.6 factor as the UnitFig converters, so any answer verifies against the matching tool.

Last Updated 2026 | Problems are algorithm-generated with the exact NIST/SI constants used by UnitFig converters. Answers are computed programmatically and can be verified with the matching converter.
